The presented device reduces the effort and cost of single solar cell characterization to a minimum. It enables realistic characterization of cells under sunlight within minutes. In the field of photovoltaic research the common way to characterize a single solar cell or a module is, to measure the current voltage curve. With this characteristic the performance and the degradation rate can be defined which are important for the consumer or developer. The paper consists of the system design description, a summary of the measurement results and an outline for further developments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Solar%20cell" title="Solar cell">Solar cell</a>, <a href="https://publications.waset.org/search?q=photovoltaics" title=" photovoltaics"> photovoltaics</a>, <a href="https://publications.waset.org/search?q=PV" title=" PV"> PV</a>, <a href="https://publications.waset.org/search?q=characterization." title=" characterization."> characterization.</a> </p> <a href="https://publications.waset.org/10007050/an-approach-on-the-design-of-a-solar-cell-characterization-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10007050/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10007050/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10007050/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10007050/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10007050/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10007050/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10007050/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10007050/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10007050/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10007050/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10007050.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">942</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1187</span> The Effect of a Graded Band Gap Window on the Performance of a Single Junction AlxGa1-xAs/GaAs Solar Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Morteza%20Fathipour">Morteza Fathipour</a>, <a href="https://publications.waset.org/search?q=Atousa%20Elahidoost"> Atousa Elahidoost</a>, <a href="https://publications.waset.org/search?q=Alireza%20Mojab"> Alireza Mojab</a>, <a href="https://publications.waset.org/search?q=Vala%20Fathipour"> Vala Fathipour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have modeled the effect of a graded band gap window on the performance of a single junction AlxGa1-xAs/GaAs solar cell.

The result from the experiment showed that solar cell began to work and distribute the current into the system when the solar energy intensity was 340 w/m2, starting from 8:00 am to 4:00 pm (duration of 8 hours). 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-watt fluorescent lamp bulbs, which was altogether 396W. In the meantime, the AC to DC power converter generated 3.55A to the load, and gave 781VA.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Solar%20Cell" title="Solar Cell">Solar Cell</a>, <a href="https://publications.waset.org/search?q=Solar-cell%20power%20generating%20system." title=" Solar-cell power generating system."> Solar-cell power generating system.</a> </p> <a href="https://publications.waset.org/9998242/the-evaluation-of-electricity-generation-and-consumption-from-solar-generator-a-case-study-at-rajabhat-suan-sunandhas-learning-center-in-samutsongkram" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/9998242/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/9998242/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/9998242/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/9998242/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/9998242/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/9998242/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/9998242/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/9998242/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/9998242/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/9998242/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/9998242.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">2077</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1185</span> Design of a Compact Meshed Antennas for 5G Communication Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Chokri%20Baccouch">Chokri Baccouch</a>, <a href="https://publications.waset.org/search?q=Chayma%20Bahhar"> Chayma Bahhar</a>, <a href="https://publications.waset.org/search?q=Hedi%20Sakli"> Hedi Sakli</a>, <a href="https://publications.waset.org/search?q=Nizar%20Sakli"> Nizar Sakli</a>, <a href="https://publications.waset.org/search?q=Taoufik%20Aguili"> Taoufik Aguili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>This paper presents a hybrid system solar cell antenna for 5G mobile communications networks.

This approximation is based on hyperbolic dependence of a current of p-n junctions on voltage for large currents. Such empirical approximation is compared with the early proposed formal linearly-hyperbolic approximation of a solar cell. The expressions defining laws of change of parameters of formal approximation at change of a photo current of family of characteristics are received. It allows simplifying a finding of parameters of approximation on actual curves, to specify their values. Analytical calculation of load regime for linearly - hyperbolic model leads to quadratic equation. Also, this model allows to define soundly a deviation from the maximum power regime and to compare efficiency of regimes of solar cells with different parameters.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=a%20solar%20cell%20generator" title="a solar cell generator">a solar cell generator</a>, <a href="https://publications.waset.org/search?q=I%20%E2%88%92%20V%20characteristic" title=" I − V characteristic"> I − V characteristic</a>, <a href="https://publications.waset.org/search?q=p%20%E2%88%92%20n%20junction" title=" p − n junction"> p − n junction</a>, <a href="https://publications.waset.org/search?q=approximation" title=" approximation"> approximation</a> </p> <a href="https://publications.waset.org/5024/an-empirical-validation-of-the-linear-hyperbolic-approximation-of-the-i-v-characteristic-of-a-solar-cell-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/5024/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/5024/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/5024/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/5024/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/5024/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/5024/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/5024/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/5024/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/5024/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/5024/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/5024.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">1436</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1179</span> Comparative Study of Two New Configurations of Solar Photovoltaic Thermal Collectors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=K.%20Touafek">K.

The disadvantage of a conventional photovoltaic cell is that its performance decreases as the temperature increases. Indeed, part of the solar radiation is converted into electricity and is dissipated as heat, increasing the temperature of the photovoltaic cell with respect to the ambient temperature. The objective of this work is to study experimentally and implement a hybrid prototype to evaluate electrical and thermal performance. In this paper, an experimental study of two new configurations of hybrid collectors is exposed. The results are given and interpreted.

Solar energy can be converted directly into electricity via photovoltaic solar cells. Thin-film solar cells are preferred due to their cost effectiveness, less material consumption, flexibility, and rising trend in efficiency. In this paper, Gallium arsenide (GaAs), Amorphous silicon (a-Si), Copper Indium Gallium Selenide (CIGS), and Cadmium Telluride (CdTe) thin film solar cells are reviewed. The evolution, structures, fabrication methods, stability and degradation methods, and trend in the efficiency of the thin-film solar cells over the years are discussed in detail. Also, a comparison of the thin-film solar cells reviewed with crystalline silicon in terms of physical properties and performance is made.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Climate%20change" title="Climate change">Climate change</a>, <a href="https://publications.waset.org/search?q=conversion%20efficiency" title=" conversion efficiency"> conversion efficiency</a>, <a href="https://publications.waset.org/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/search?q=thin-film%20solar%20cell." title=" thin-film solar cell."> thin-film solar cell.</a> </p> <a href="https://publications.waset.org/10012880/a-review-of-current-trends-in-thin-film-solar-cell-technologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10012880/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10012880/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10012880/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10012880/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10012880/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10012880/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10012880/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10012880/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10012880/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10012880/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10012880.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">1297</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1173</span> Comparison between the Efficiency of Heterojunction Thin Film InGaP\GaAs\Ge and InGaP\GaAs Solar Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=F.%20Djaafar">F.

An initial dual junction InGaP/GaAs model of a previous published heterojunction cell was simulated in Tcad Silvaco to accurately predict solar cell performance. To improve the solar cell’s performance, we have fixed meshing, material properties, models and numerical methods. However, thickness and layer doping concentration were taken as variables. We, first simulate the InGaP\GaAs dual junction cell by changing the doping concentrations and thicknesses which showed an increase in efficiency. Next, a triple junction <em>InGaP/GaAs/Ge </em>cell was modeled by adding a Ge layer to the previous dual junction InGaP/GaAs model with an InGaP /GaAs tunnel junction.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Heterojunction" title="Heterojunction">Heterojunction</a>, <a href="https://publications.waset.org/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/search?q=thin%20film" title=" thin film"> thin film</a>, <a href="https://publications.waset.org/search?q=Tcad%20Silvaco." title=" Tcad Silvaco."> Tcad Silvaco.</a> </p> <a href="https://publications.waset.org/10006842/comparison-between-the-efficiency-of-heterojunction-thin-film-ingapgaasge-and-ingapgaas-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10006842/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10006842/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10006842/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10006842/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10006842/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10006842/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10006842/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10006842/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10006842/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10006842/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10006842.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">1255</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1172</span> Modeling of Silicon Solar Cell with Anti-Reflecting Coating</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Ankita%20Gaur">Ankita Gaur</a>, <a href="https://publications.waset.org/search?q=Mouli%20Karmakar"> Mouli Karmakar</a>, <a href="https://publications.waset.org/search?q=Shyam"> Shyam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> <p>In this study, a silicon solar cell has been modeled and analyzed to enhance its performance by improving the optical properties using an anti-reflecting coating (ARC).

The model is tested with various anti-reflective coatings and the performance has also been compared with uncoated cells. ARC improves the optical transmittance of the photon. Higher transmittance of ⁓96.57% with lowest reflectance of ⁓ 1.74% at 12.00 hours was obtained with MgF2 coated silicon cells.

A small amount of additive deionized water (DI-H<sub>2</sub>O) was added into PbI<sub>2</sub> + Dimethyl formamide (DMF) precursor solution in order to increase the solubility of PbI<sub>2</sub> in DMF, and finally to manipulate the surface morphology of the perovskite films. A morphology transition from needle like structure to hexagonal plates, and then needle-like again has been observed as the DI-H2O was added continuously (0.0 wt% to 3.0wt%). The latter one leads to full surface coverage of the perovskite, which is essential for high performance solar cell. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Charge%20carrier%20diffusion%20lengths" title="Charge carrier diffusion lengths">Charge carrier diffusion lengths</a>, <a href="https://publications.waset.org/search?q=methylamonium%20lead%20iodide" title=" methylamonium lead iodide"> methylamonium lead iodide</a>, <a href="https://publications.waset.org/search?q=precursor%20composition" title=" precursor composition"> precursor composition</a>, <a href="https://publications.waset.org/search?q=perovskite%20solar%20cell" title=" perovskite solar cell"> perovskite solar cell</a>, <a href="https://publications.waset.org/search?q=sequential%20deposition." title=" sequential deposition."> sequential deposition.</a> </p> <a href="https://publications.waset.org/10005131/morphology-study-of-inverted-planar-heterojunction-perovskite-solar-cells-in-sequential-deposition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10005131/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10005131/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10005131/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10005131/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10005131/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10005131/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10005131/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10005131/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10005131/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10005131/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10005131.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">1689</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1169</span> Effective Cooling of Photovoltaic Solar Cells by Inserting Triangular Ribs: A Numerical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=S.%20Saadi">S.

A large amount of solar radiation is converted to heat, which should be dissipated by any cooling techniques. In the present study, the cooling is achieved by inserting triangular ribs in the duct. A comprehensive two-dimensional thermo-fluid model for the effective cooling of PV cells has been developed. It has been first carefully validated against experimental and numerical results available in the literature. A parametric analysis was then carried out about the influence of the number and size of the ribs, wind speed, solar irradiance and inlet fluid velocity on the average solar cell and outlet air temperatures as well as the thermal and electrical efficiencies of the module. Results indicated that the use of triangular ribbed channels is a very effective cooling technique, which significantly reduces the average temperature of the PV cell, especially when increasing the number of ribs.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Effective%20cooling" title="Effective cooling">Effective cooling</a>, <a href="https://publications.waset.org/search?q=numerical%20modeling" title=" numerical modeling"> numerical modeling</a>, <a href="https://publications.waset.org/search?q=photovoltaic%20cell" title=" photovoltaic cell"> photovoltaic cell</a>, <a href="https://publications.waset.org/search?q=triangular%20ribs." title=" triangular ribs.

Solar Cell as a basement of solar system has attracted lots of research. To conduct a study about solar energy system, an authenticated model is required. Diode base PV models are widely used by researchers. These models are classified based on the number of diodes used in them. Single and two-diode models are well studied. Single-diode models may have two, three or four elements. In this study, these solar cell models are examined and the simulation results are compared to each other. All PV models are re-designed in the Matlab/Simulink software and they examined by certain test conditions and parameters. This paper provides comparative studies of these models and it tries to compare the simulation results with manufacturer-s data sheet to investigate model validity and accuracy. The results show a four- element single-diode model is accurate and has moderate complexity in contrast to the two-diode model with higher complexity and accuracy <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Fill%20Factor%20%28FF%29" title="Fill Factor (FF)">Fill Factor (FF)</a>, <a href="https://publications.waset.org/search?q=Matlab%2FSimulink" title=" Matlab/Simulink"> Matlab/Simulink</a>, <a href="https://publications.waset.org/search?q=Maximum%20PowerPoint%20%28MPP%29" title=" Maximum PowerPoint (MPP)"> Maximum PowerPoint (MPP)</a>, <a href="https://publications.waset.org/search?q=Maximum%20Power%20Point%20Tracker%20%28MPPT%29" title=" Maximum Power Point Tracker (MPPT)"> Maximum Power Point Tracker (MPPT)</a>, <a href="https://publications.waset.org/search?q=Photo%20Voltaic%28PV%29" title=" Photo Voltaic(PV)"> Photo Voltaic(PV)</a>, <a href="https://publications.waset.org/search?q=Solar%20cell" title=" Solar cell"> Solar cell</a>, <a href="https://publications.waset.org/search?q=Standard%20Test%20Condition%20%28STC%29." title=" Standard Test Condition (STC)."> Standard Test Condition (STC).</a> </p> <a href="https://publications.waset.org/4091/a-comparative-study-of-pv-models-in-matlabsimulink" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/4091/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/4091/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/4091/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/4091/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/4091/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/4091/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/4091/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/4091/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/4091/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/4091/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/4091.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">5816</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1167</span> Thermal Analysis of Photovoltaic Integrated Greenhouse Solar Dryer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Sumit%20Tiwari">Sumit Tiwari</a>, <a href="https://publications.waset.org/search?q=Rohit%20Tripathi"> Rohit Tripathi</a>, <a href="https://publications.waset.org/search?q=G.%20N.%20Tiwari"> G.

However, there is no set of calculations to select the appropriate top cell materials. Therefore, this paper will propose a simple but practical selection method. First of all, we calculate the S-Q limit and explain the reasons for developing tandem solar cells. Secondly, we calculate the theoretical energy conversion efficiency of the double-junction tandem solar cells while combining the commercial monocrystalline Si and materials' practical efficiency to consider the actual situation. Finally, we conservatively conclude that if considering 75% performance of the theoretical energy conversion efficiency of the top cell, the suitable bandgap energy range will fall between 1.38 eV to 2.5 eV. Besides, we also briefly describe some improvements of several proper materials, CZTS, CdSe, Cu2O, ZnTe, and CdS, hoping that future research can select and manufacture high-efficiency Si-based tandem solar cells based on this paper successfully. Most importantly, our calculation method is not limited to silicon solely. If other materials’ performances match or surpass silicon's ability in the future, researchers can also apply this set of deduction processes.</p> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=High-efficiency%20solar%20cells" title="High-efficiency solar cells">High-efficiency solar cells</a>, <a href="https://publications.waset.org/search?q=material%20selection" title=" material selection"> material selection</a>, <a href="https://publications.waset.org/search?q=Si-based%20double-junction%20solar%20cells" title=" Si-based double-junction solar cells"> Si-based double-junction solar cells</a>, <a href="https://publications.waset.org/search?q=tandem%20solar%20cells" title=" tandem solar cells"> tandem solar cells</a>, <a href="https://publications.waset.org/search?q=photovoltaics." title=" photovoltaics."> photovoltaics.</a> </p> <a href="https://publications.waset.org/10012488/practical-evaluation-of-high-efficiency-si-based-tandem-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10012488/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10012488/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10012488/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10012488/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10012488/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10012488/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10012488/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10012488/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10012488/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10012488/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10012488.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">568</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1162</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/search?q=Eka%20Maulana">Eka Maulana</a>, <a href="https://publications.waset.org/search?q=Sholeh%20Hadi%20Pramono"> Sholeh Hadi Pramono</a>, <a href="https://publications.waset.org/search?q=Dody%20Fanditya"> Dody Fanditya</a>, <a href="https://publications.waset.org/search?q=M.%20Julius"> M.

The results show a reduction in the short circuit current due to increasing atmospheric turbidity, it is 63.09% under global radiation.

This paper focuses on the design of a modular solar power harvesting system for a hexagonal-shaped small satellite. The designed solar power harvesting systems are composed of solar panels and power converter subsystems. The solar panel is composed of solar cells mounted on the external face of the printed circuit board (PCB), while the electronic components of power conversion are mounted on the interior side of the same PCB. The solar panel with dimensions 16.5 cm × 99 cm is composed of 36 solar cells (each solar cell is 4 cm × 7 cm) divided into four parallel banks where each bank consists of 9 solar cells. The output voltage of a single solar cell is 2.14V, and the combined output voltage of 9 series connected solar cells is around 19.3V. The output voltage of the solar panel is boosted to the satellite power distribution bus voltage level (28V) by a boost converter working on a constant voltage maximum power point tracking (MPPT) technique. The solar panel module is an eight-layer PCB having embedded coil in 4 internal layers. This coil is used to control the attitude of the spacecraft, which consumes power to generate a magnetic field and rotate the spacecraft. As power converter and distribution subsystem components are mounted on the PCB internal layer, therefore it is mandatory to do thermal analysis in order to ensure that the overall module temperature is within thermal safety limits. The main focus of the overall design is on compactness, miniaturization, and efficiency enhancement.</p> <p class="card-text"><strong>Keywords:</strong> <a
