We introduced ZnO as an alternative to TiO2 in the dye sensitized solar cells (DSSCs) due to its band gap similar to TiO2, higher electron mobility, and flexible procedures of preparations. Dye-sensitized solar cells (DSSCs) based on Terminalia catappa L. was extracted in water (A), ethanol (B) and the mixture of ethanol and water in the ratio 1:1by volume (C). The best performance Solar cells sensitized was from extracts A and achieved up to Jsc 1.51 mAcm−2, Voc 0.75V, FF 0.88 and η 0.63%. We notice that as pHs decreases there is the increase in DSSC efficiency. There is Long period stability in efficiency of the cells prepared using A than in C and a fair stability in efficiency of B cell. The results obtained with extracts B and C confirmed that Ethanol with water could not be considered as a suitable solvent for the extraction of natural dye. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zinc%20oxide" title="zinc oxide">zinc oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=dye-sensitized%20solar%20cell" title=" dye-sensitized solar cell"> dye-sensitized solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=terminalia%20catappa%20L." title=" terminalia catappa L."> terminalia catappa L.</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO2" title=" TiO2 "> TiO2 </a> </p> <a href="https://publications.waset.org/abstracts/37893/the-stability-and-performances-of-terminalia-catappa-l-dye-sensitized-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37893.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">402</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4977</span> Electrical Properties of Roystonea regia Fruit Extract as Dye Sensitized Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adenike%20Boyo%20Olasunkanmi%20Kesinro">Adenike Boyo Olasunkanmi Kesinro</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%20Boyo"> Henry Boyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Surukite%20Oluwole"> Surukite Oluwole</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Utilizing solar energy in producing electricity can minimize environmental pollution generated by fossil fuel in producing electricity. Our research was base on the extraction of dye from Roystonea regia fruit by using methanol as solvent. The dye extracts were used as sensitizers in Dye-sensitized solar cell (DSSCs). Study was done on the electrical properties from the extracts of Roystonea regia fruit as Dye-sensitized solar cell (DSSCs). The absorptions of the extracts and extracts with dye were determined at different wavelengths (350-1000nm). Absorption peak was observed at 1.339 at wavelength 400nm. The obtained values for methanol extract Roystonea regia extract are, Imp = 0.015mA, Vmp = 12.0mV, fill factor = 0.763, Isc= 0.018 mA and Voc = 13.1 mV and efficiency of 0.32%. .The phytochemical screening was taken and it was observed that Roystonea regia extract contained less of anthocyanin compared to flavonoids. The nanostructured dye sensitized solar cell (DSSC) will provide economically credible alternative to present day silicon p–n junction photovoltaic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=methanol" title="methanol">methanol</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=titanium%20dioxide" title=" titanium dioxide"> titanium dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=roystonea%20regia%20fruit" title=" roystonea regia fruit"> roystonea regia fruit</a>, <a href="https://publications.waset.org/abstracts/search?q=dye-sensitized%20solar%20cell" title=" dye-sensitized solar cell"> dye-sensitized solar cell</a> </p> <a href="https://publications.waset.org/abstracts/10325/electrical-properties-of-roystonea-regia-fruit-extract-as-dye-sensitized-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10325.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">405</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4976</span> Beneficiation of Dye Sensitized Solar Cell as Energy Saving from Apple Skin with TiO2 Electrolysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Astari%20Indarsari">Astari Indarsari</a>, <a href="https://publications.waset.org/abstracts/search?q=Bastian%20B.%20Purba"> Bastian B.

The multidentate monoanionic ligand [S₂PFc(OH)]¯ (L1) was synthesized from the reaction between ferrocenyl Lawesson’s reagent, [FcP(=S)μ-S]₂ (FcLR), (Fc = ferrocenyl) and water. Ligand L1 could potentially coordinate to metal centers through the S, S’ and O donor atoms. The reaction between metal salt precursors and L1 produced a Ni(II) complex of the type [Ni{S₂P(Fc)(OH)}₂] (1) (molar ratio 1:2), a tetranickel (II) complex of the type [Ni₂{S₂OP(Fc)}₂]₂ (2) (molar ratio (1:1), as well as a Zn(II) complex [Zn{S₂P(Fc)(OH)}₂]₂ (3), and a Cd(II) complex [Cd{S₂P(Fc)(OH)}₂]₂ (4). Complexes 1-4 were characterized by 1H and 31P NMR and FT-IR, and complexes 1 and 2 were additionally analysed by X-Ray crystallography. After co-sensitization, the DSSCs were characterized using UV-Vis, cyclic voltammetry, electrochemical impedance spectroscopy, and photovoltaic measurements (I-V curves). Overall finding shows that co-sensitization of our compounds with ruthenium dye N719 resulted in a better overall solar conversion efficiency than only pure N719 dye under the same experimental conditions. In conclusion, we report the first examples of dye-sensitized solar cells (DSSCs) co-sensitized with ferrocenyl dithiophosphonate complexes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dithiophosphonate" title="dithiophosphonate">dithiophosphonate</a>, <a href="https://publications.waset.org/abstracts/search?q=dye%20sensitized%20solar%20cell" title=" dye sensitized solar cell"> dye sensitized solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=co-sensitization" title=" co-sensitization"> co-sensitization</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20efficiency" title=" solar efficiency"> solar efficiency</a> </p> <a href="https://publications.waset.org/abstracts/99644/heterodimetallic-ferrocenyl-dithiophosphonate-complexes-of-nickelii-zincii-and-cadmiumii-as-high-efficiency-co-sensitizers-in-dye-sensitized-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99644.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4973</span> Additive Carbon Dots Nanocrystals for Enhancement of the Efficiency of Dye-Sensitized Solar Cell in Energy Applications Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Getachew%20Kuma%20Watiro">Getachew Kuma Watiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The need for solar energy is constantly increasing and it is widely available on the earth’s surface. Photovoltaic technology is one of the most capable of all viable energy technology and is seen as a promising approach to the control era as it is readily available and has zero carbon emissions. Inexpensive and versatile solar cells have achieved the conversion efficiency and long life of dye-sensitized solar cells, improving the conversion efficiency from the sun to electricity. DSSCs have received a lot of attention for Various potential commercial uses, such as mobile devices and portable electronic devices, as well as integrated solar cell modules. The systematic reviews were used to show the critical impact of additive C-dots in the Dye-Sensitized solar cell for energy application technology. This research focuses on the following methods to synthesize nanoparticles such as facile, polyol, calcination, and hydrothermal technique. In addition to these, there are additives C-dots by the Hydrothermal method. This study deals with the progressive development of DSSC in photovoltaic technology. The applications of single and heterojunction structure technology devices were used (ZnO, NiO, SnO2, and NiO/ZnO/N719) and applied some additives C-dots (ZnO/C-dots /N719, NiO/C-dots /N719, SnO2 /C-dots /N719 and NiO/ZnO/C-dots/N719) and the effects of C-dots were reviewed. More than all, the technology of DSSC with C-dots enhances efficiency. Finally, recommendations have been made for future research on the application of DSSC with the use of these additives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dye-sensitized%20solar%20cells" title="dye-sensitized solar cells">dye-sensitized solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=heterojunction%E2%80%99s%20structure" title=" heterojunction’s structure"> heterojunction’s structure</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dot" title=" carbon dot"> carbon dot</a>, <a href="https://publications.waset.org/abstracts/search?q=conversion%20efficiency" title=" conversion efficiency"> conversion efficiency</a> </p> <a href="https://publications.waset.org/abstracts/149846/additive-carbon-dots-nanocrystals-for-enhancement-of-the-efficiency-of-dye-sensitized-solar-cell-in-energy-applications-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149846.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">119</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4972</span> Effect of Chlorophyll Concentration Variations from Extract of Papaya Leaves on Dye-Sensitized Solar Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eka%20Maulana">Eka Maulana</a>, <a href="https://publications.waset.org/abstracts/search?q=Sholeh%20Hadi%20Pramono"> Sholeh Hadi Pramono</a>, <a href="https://publications.waset.org/abstracts/search?q=Dody%20Fanditya"> Dody Fanditya</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Julius"> M.

The synthesized dye together with its corresponding intermediates were purified and characterized by analytical techniques. Such techniques confirmed the corresponding structures of dye and its intermediate and the yield of all the stages of dye preparation were calculated to be above 85%. Fluorometric analyses show fluorescence in the green region of the visible spectrum for dye. Oxidation potential measurements for dye ensured an energetically permissible and thermodynamically favourable charge transfer throughout the continuous cycle of photo-electric conversion. Finally, dye sensitized solar cells were fabricated in order to determine the photovoltaic behaviour and conversion efficiencies of dye. Such evaluations demonstrate rather medium conversion efficiencies of 2.33% for such simple structured synthesized dye. Such conversion efficiencies demonstrate the potentiality of future use of such dye structures in dye-sensitized solar cells with respect to low material costs, ease of molecular tailoring, high yields of reactions, high performance and ease of recyclability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conversion%20efficiency" title="conversion efficiency">conversion efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=Dye-sensitized%20solar%20cells" title=" Dye-sensitized solar cells"> Dye-sensitized solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=indigo" title=" indigo"> indigo</a>, <a href="https://publications.waset.org/abstracts/search?q=photonic%20material" title=" photonic material"> photonic material</a> </p> <a href="https://publications.waset.org/abstracts/16232/synthesis-of-novel-organic-dyes-based-on-indigo-for-dye-sensitized-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16232.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">368</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4970</span> Investigation of Graphene-MoS₂ Nanocomposite as Counter Electrode in Dye-Sensitized Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mozhgan%20Hosseinnezhad">Mozhgan Hosseinnezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamaladin%20Gharanjig"> Kamaladin Gharanjig</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Ghahari"> Mehdi Ghahari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dye-sensitized solar cells are sustainable tool for generating electrical energy using sunlight. To develop this technology, obstacles such as cost and the use of expensive compounds must be overcome. Herein, we employed a MoS₂/graphene composite instead of platinum in the DSSCs. Platinum is an efficient and conventional counter electrode in the preparation of DSSCs, for this purpose, the effect of the presence of platinum electrode was also studied under similar conditions. The prepared nanocomposite product was checked by analysis methods to confirm the correctness of the construction and the desired structure.

We present the preparation of NiO by electrodeposition from pure polar aprotic medium and mixtures with water. The effect of the solvent, of the electrochemical deposition parameters and post-deposition annealing treatment on the structural, morphological and optical properties of the films is investigated. We remarkably show that the solvent is inserted in the deposited layer and act as a blowing agent, giving rise to mesoporous films after elimination by thermal annealing. These layers of p-type oxide have been successfully used, after sensitization by a dye, in p-type dye-sensitized solar cells. The effects of the solvent on the layer properties and the application of these layers in p-type dye-sensitized solar cells are described. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NiO" title="NiO">NiO</a>, <a href="https://publications.waset.org/abstracts/search?q=layer" title=" layer"> layer</a>, <a href="https://publications.waset.org/abstracts/search?q=p-type%20sensitized%20solar%20cells" title=" p-type sensitized solar cells"> p-type sensitized solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodeposition" title=" electrodeposition"> electrodeposition</a> </p> <a href="https://publications.waset.org/abstracts/66597/electrodeposition-of-nio-films-from-organic-solvent-based-electrolytic-solutions-for-solar-cell-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66597.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">297</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4967</span> Development of Dye Sensitized Solar Window by Physical Parameters Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tahsin%20Shameem">Tahsin Shameem</a>, <a href="https://publications.waset.org/abstracts/search?q=Chowdhury%20Sadman%20Jahan"> Chowdhury Sadman Jahan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Alam"> Mohammad Alam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Interest about Net Zero Energy Buildings have gained traction in recent years following the need to sustain energy consumption with generations on site and to reduce dependence on grid supplied energy from large plants using fossil fuel. With this end in view, building integrated photovoltaics are being studied attempting to utilize all exterior facades of a building to generate power. In this paper, we have looked at the physical parameters defining a dye sensitized solar cell (DSSC) and discussed their impact on energy harvest. Following our discussion and experimental data obtained from literature, we have attempted to optimize these physical parameters accordingly so as to allow maximum light absorption for a given active layer thickness. We then modified a planer DSSC design with our optimized properties to allow adequate light transmission which demonstrated a high fill factor and an External Quantum Efficiency (EQE) of greater than 9% by computer aided design and simulation. In conclusion, a DSSC based solar window with such high output values even after such high light transmission through it definitely flags a promising future for this technology and our work elicits the need for further study and practical experimentation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=net%20zero%20energy%20building" title="net zero energy building">net zero energy building</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20photovoltaics" title=" integrated photovoltaics"> integrated photovoltaics</a>, <a href="https://publications.waset.org/abstracts/search?q=dye%20sensitized%20solar%20cell" title=" dye sensitized solar cell"> dye sensitized solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=fill%20factor" title=" fill factor"> fill factor</a>, <a href="https://publications.waset.org/abstracts/search?q=External%20Quantum%20Efficiency" title=" External Quantum Efficiency"> External Quantum Efficiency</a> </p> <a href="https://publications.waset.org/abstracts/122281/development-of-dye-sensitized-solar-window-by-physical-parameters-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122281.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4966</span> Investigation of Green Dye-Sensitized Solar Cells Based on Natural Dyes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Hosseinnezhad">M.

Spectrophotometric studies of the natural dyes in solution and on a titanium dioxide substrate were carried out in order to assess changes in the status of the dyes. The results show that the bathochromic shift is seen on the photo-electrode substrate. The chemical binding of the natural dyes at the surface photo-electrode were increased by the chelating effect of the Ti(IV) ions. The cyclic voltammetry results showed that all extracts are suitable to be performed in DSSCs. Finally, photochemical performance and stability of DSSCs based on natural dyes were studied. The DSSCs sensitized by black carrot extract have been reported to achieve up to Jsc=1.17 mAcm<sup>-2</sup>, Voc= 0.55 V, FF= 0.52, η=0.34%, whereas Bramble extract can obtain up to Jsc=2.24 mAcm<sup>-2</sup>, Voc= 0.54 V, FF= 0.57, η=0.71%. The power conversion efficiency was obtained from the mixed dyes in DSSCs. The power conversion efficiency of dye-sensitized solar cells using mixed Black carrot and Bramble dye is the average of the their efficiency in single DSSCs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthocyanin" title="anthocyanin">anthocyanin</a>, <a href="https://publications.waset.org/abstracts/search?q=dye-sensitized%20solar%20cells" title=" dye-sensitized solar cells"> dye-sensitized solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20energy" title=" green energy"> green energy</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20materials" title=" optical materials"> optical materials</a> </p> <a href="https://publications.waset.org/abstracts/58409/investigation-of-green-dye-sensitized-solar-cells-based-on-natural-dyes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58409.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">245</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4965</span> Synthesis, Characterization and Applications of Some Selected Dye-Functionalized P and N-Type Nanoparticles in Dye Sensitized Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arifa%20Batool">Arifa Batool</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghulam%20Hussain%20Bhatti"> Ghulam Hussain Bhatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Mujtaba%20Shah"> Syed Mujtaba Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inorganic n-type (TiO2, CdO) and p-type (NiO, CuO) metal oxide nanoparticles were synthesized by a facile wet chemical method at room temperature.

Muthukumarasamy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dye sensitized solar cell (DSSC) has become a significant research area due to their fundamental and scientific importance in the area of energy conversion. Synthetic dyes as sensitizer in DSSC are efficient and durable but they are costlier, toxic and have the tendency to degrade. Natural sensitizers contain plant pigments such as anthocyanin, carotenoid, flavonoid, and chlorophyll which promote light absorption as well as injection of charges to the conduction band of TiO2 through the sensitizer. But, the efficiency of natural dyes is not up to the mark mainly due to instability of the pigment such as anthocyanin. The stability issues in vitro are mainly due to the effect of solvents on extraction of anthocyanins and their respective pH. Taking this factor into consideration, in the present work, the anthocyanins were extracted from the flower Caesalpinia pulcherrima (C. pulcherrimma) with various solvents and their respective stability and pH values are discussed. The usage of citric acid as solvent to extract anthocyanin has shown good stability than other solvents. It also helps in enhancing the sensitization properties of anthocyanins with Titanium dioxide (TiO2) nanorods. The IPCE spectra show higher photovoltaic performance for dye sensitized TiO2nanorods using citric acid as solvent. The natural DSSC using citric acid as solvent shows a higher efficiency compared to other solvents. Hence citric acid performs to be a safe solvent for natural DSSC in boosting the photovoltaic performance and maintaining the stability of anthocyanins. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caesalpinia%20pulcherrima" title="Caesalpinia pulcherrima">Caesalpinia pulcherrima</a>, <a href="https://publications.waset.org/abstracts/search?q=citric%20acid" title=" citric acid"> citric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=dye%20sensitized%20solar%20cells" title=" dye sensitized solar cells"> dye sensitized solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO%E2%82%82%20nanorods" title=" TiO₂ nanorods"> TiO₂ nanorods</a> </p> <a href="https://publications.waset.org/abstracts/71483/effect-of-solvents-in-the-extraction-and-stability-of-anthocyanin-from-the-petals-of-caesalpinia-pulcherrima-for-natural-dye-sensitized-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71483.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4963</span> Optimized Dye-Sensitized Solar Cell Using Natural Dye and Counter Electrode from Robusta Coffee Beans Peel Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tomi%20Setiawan">Tomi Setiawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Wahyu%20Y.%20Subekti"> Wahyu Y.

DSSC has two important parts of dye and counter electrode. Anthocyanin compounds in the coffee beans peel can be potential as natural dye and also counter electrodes as activated carbon in the DSSC system. The purpose of this research is to find out how to isolate Anthocyanin, manufacture of counter electrode, and to know the efficiency of counter electrode produced from the coffee pulp waste in DSSC prototype. In this research we used 2 x 2 cm FTO glass coated carbon paste with a thickness variation of 100 μL, 200 μL and 300 μL as counter electrode and other FTO glass coated with TiO₂ paste as work electrode, then two FTO glasses are connected to form a sandwich-liked structure and add Triiodide electrolyte solution in its gap, thus forming a DSSC prototype. The results showed that coffee pulp waste contains anthocyanin of 12.23 mL/80gr and it can produce activated carbon. The characterization performed shows that the UV-Vis Anthocyanin result is at wavelength of ultra violet area that is 219,50 nm with absorbance value equal to 1,469, and maximum wavelength at visible area is 720,00 nm with absorbance value equal to 0,013. The functional groups contained in the anthocyanin are O-H groups at wave numbers 3385.60 cm⁻¹, C = O groups at wave numbers 1618.63 cm⁻¹, and C-O-C groups at 1065.40 cm⁻¹ wave numbers.

The highest intensity read during the experiment was 1,051.64w/m2. The solar power was 38.74kWh/day. The electromotive force from solar cell averagely was 93.6V. However, when connecting solar cell with the battery charge controller system, the voltage was dropped to 69.07V. After evaluating the power distribution ability and electricity load of tested solar cell, the result showed that it could generate power to 11 units of 36-wattfluorescent lamp bulbs, which was altogether 396W.

The cell's structure allows silicon solar cells to surpass the 25% efficiency barrier and interdigitated solar cells are now the most efficient. In this work, the fabrication of a light, efficient and temperature resistant interdigitated back contact (IBC) solar cell is investigated. This form of solar cell differs from a conventional solar cell in that the electrodes are located at the back of the cell, eliminating the need for grids on the top, allowing the full surface area of the cell to receive sunlight, resulting in increased efficiency. In this project, we will use SILVACO TCAD, an optoelectronic device simulator, to construct a very thin solar cell with dimensions of 100x250um in 2D Luminous. The influence of sunlight intensity and atmospheric temperature on solar cell output power is highly essential and it has been explored in this work. The cell's optimum performance with 150um bulk thickness provides 28.81% efficiency with an 87.68% fill factor rate making it very thin, flexible and resilient, providing diverse operational capabilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interdigitated" title="interdigitated">interdigitated</a>, <a href="https://publications.waset.org/abstracts/search?q=shading" title=" shading"> shading</a>, <a href="https://publications.waset.org/abstracts/search?q=recombination%20loss" title=" recombination loss"> recombination loss</a>, <a href="https://publications.waset.org/abstracts/search?q=incident-plane" title=" incident-plane"> incident-plane</a>, <a href="https://publications.waset.org/abstracts/search?q=drift-diffusion" title=" drift-diffusion"> drift-diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=luminous" title=" luminous"> luminous</a>, <a href="https://publications.waset.org/abstracts/search?q=SILVACO" title=" SILVACO"> SILVACO</a> </p> <a href="https://publications.waset.org/abstracts/146112/modelling-and-simulation-of-light-and-temperature-efficient-interdigitated-back-surface-contact-solar-cell-with-2881-efficiency-rate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146112.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4955</span> Effects of the Ambient Temperature and the Defect Density on the Performance the Solar Cell (HIT)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bouzaki%20Mohammed%20Moustafa">Bouzaki Mohammed Moustafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Benyoucef%20Boumediene"> Benyoucef Boumediene</a>, <a href="https://publications.waset.org/abstracts/search?q=Benouaz%20Tayeb"> Benouaz Tayeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Benhamou%20Amina"> Benhamou Amina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ambient temperature and the defects density in the Hetero-junction with Intrinsic Thin layers solar cells (HIT) strongly influence their performances.

Over the past 20 years, the main efforts have attempted to enhance the efficiency of n-type DSSCs, the highest efficiency record of 14.30% was achieved using the co-sensitization of two metal-free organic dyes and Co (II/III) tris(phenanthroline)-based redox electrolyte. In the last years, the development of the efficient p-type DSSC has become a research focus owing to the fact that the concept of tandem solar cell was proposed as the solution to increase the power conversion efficiency. A promising alternative for the photocathodes of p-type DSSC, cuprous (Cu2O) and cupric (CuO) oxides have been investigated because of its nontoxic nature, low cost, high natural abundance, a good absorption coefficient for visible light and a higher dielectric constant than NiO. In case of p-type DSSC based on copper oxides with I3-/I- as redox mediator, the highest conversion efficiency of 0.42% (Cu2O) and 0.03% (CuO) has achieved. Towards the increase in the performance, we have fabricated and analyzed the performance of p-type DSSC prepared with the binder-free porous Cu2O photocathodes. Porous thin film could be an attractive alternative for DSSC because of their large surface areas which enable the efficient absorption of the dyes and light. We propose a simple and one-step hydrothermal method for the preparation of porous Cu2O thin film using copper substrate, cupric acetate and ethyl cellulose. The cubic structure of Cu2O has been determined by X-ray diffraction (XRD) and porous morphology of thin film was emphasized by Scanning Electron Microscope Inspect S (SEM). Optical and Mott-Schottky measurements attest of the high quality of the Cu2O thin film. The binder-free porous Cu2O photocathode has confirmed the excellent photovoltaic properties, the best value reported for p-type DSSC (1%) in similar conditions being reached. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cuprous%20oxide" title="cuprous oxide">cuprous oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=dye-sensitized%20solar%20cell" title=" dye-sensitized solar cell"> dye-sensitized solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrothermal%20method" title=" hydrothermal method"> hydrothermal method</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20photocathode" title=" porous photocathode"> porous photocathode</a> </p> <a href="https://publications.waset.org/abstracts/90659/binder-free-porous-photocathode-based-on-cuprous-oxide-for-high-performing-p-type-dye-sensitized-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90659.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4952</span> Numerical Simulation of Multijunction GaAs/CIGS Solar Cell by AMPS-1D</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassane%20Ben%20Slimane">Hassane Ben Slimane</a>, <a href="https://publications.waset.org/abstracts/search?q=Benmoussa%20Dennai"> Benmoussa Dennai</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderrahman%20Hemmani"> Abderrahman Hemmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderrachid%20Helmaoui"> Abderrachid Helmaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the past few years a great variety of multi-junction solar cells has been developed with the aim of a further increase in efficiency beyond the limits of single junction devices.

To fabricate a hydrogenated silicon thin film using sputtering process for solar cell applications, the ion bombardment during sputtering will generate microstructures (voids and columnar structures) to form silicon dihydride bodings as defects. The properties of heterojunction silicon solar cells were studied by using boron grains and silicon-boron targets. Finally, an 11.7% efficiency of solar cell was achieved by using all sputtering process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20cell" title="solar cell">solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=sputtering%20process" title=" sputtering process"> sputtering process</a>, <a href="https://publications.waset.org/abstracts/search?q=pvd" title=" pvd"> pvd</a>, <a href="https://publications.waset.org/abstracts/search?q=alloy%20target" title=" alloy target"> alloy target</a> </p> <a href="https://publications.waset.org/abstracts/30724/fabrication-of-silicon-solar-cells-using-all-sputtering-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30724.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">580</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4949</span> Effect of Methylammonium Lead Iodide Layer Thickness on Performance of Perovskite Solar Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chadel%20Meriem">Chadel Meriem</a>, <a href="https://publications.waset.org/abstracts/search?q=Bensmaine%20Souhila"> Bensmaine Souhila</a>, <a href="https://publications.waset.org/abstracts/search?q=Chadel%20Asma"> Chadel Asma</a>, <a href="https://publications.waset.org/abstracts/search?q=Bouchikhi%20Chaima"> Bouchikhi Chaima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Methylammonium Lead Iodide CH3NH3PbI3 is used in solar cell as an absorber layer since 2009. The efficiencies of these technologies have increased from 3.8% in 2009 to 29.15% in 2019. So, these technologies Methylammonium Lead Iodide is promising for the development of high-performance photovoltaic applications. Due to the high cost of the experimental of the solar cells, researchers have turned to other methods like numerical simulation. In this work, we evaluate and simulate the performance of a CH₃NH₃PbI₃ lead-based perovskite solar cell when the amount of materials of absorber layer is reduced. We show that the reducing of thickness the absorber layer influent on performance of the solar cell. For this study, the one-dimensional simulation program, SCAPS-1D, is used to investigate and analyze the performance of the perovskite solar cell. After optimization, maximum conversion efficiency was achieved with 300 nm in absorber layer. <p class="card-text"><strong>Keywords:</strong> <a
