heterojunction solar cell (BHJ) P3HT: PCBM. We have studied the influence of their parameters on cell characteristics. For this purpose, we used the effective medium model and the solar cell simulator (SCAPS) to model the characteristics of the solar cell. We also explore the transport of charge carriers in the device. It was assumed that the mixture is lightly p-type doped and that the band gap contains acceptor defects near the HOMO level with a Gaussian distribution of energy states at 100 and 50 meV. We varied defects density between 1012-1017 cm-3, from 1016 cm-3, a total decrease of the photovoltaic characteristics due to the increase of the non-radiative recombination can be noticed. Then we studied the effect of variation of the electron and the hole capture cross-section on the cell’s performance, we noticed that the cell obtains a better efficiency of about 3.6% for an electron capture cross section ≤ 10-15 cm2 and a hole capture cross section ≤ 10-19 cm2. On the other hand, we also varied the temperature between 120K and 400K. We observed that the temperature of the solar cell induces a noticeable effect on its voltage. While the effect of temperature on the solar cell current is negligible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20solar%20cell" title="organic solar cell">organic solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=P3HT%3APCBM" title=" P3HT:PCBM"> P3HT:PCBM</a>, <a href="https://publications.waset.org/abstracts/search?q=defects" title=" defects"> defects</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=SCAPS" title=" SCAPS"> SCAPS</a> </p> <a href="https://publications.waset.org/abstracts/164758/modeling-and-simulation-of-organic-solar-cells-based-on-p3htpcbm-using-scaps-1-d-influence-of-defects-and-temperature-on-the-performance-of-the-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164758.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">91</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">9</span> DFT and SCAPS Analysis of an Efficient Lead-Free Inorganic CsSnI₃ Based Perovskite Solar Cell by Modification of Hole Transporting Layer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyedeh%20Mozhgan%20Seyed%20Talebi">Seyedeh Mozhgan Seyed Talebi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih%20-Hao%20Lee"> Chih -Hao Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With an abrupt rise in the power conservation efficiency (PCE) of perovskite solar cells (PSCs) within a short span of time, the toxicity of lead was raised as a major hurdle in the path toward their commercialization. In the present research, a systematic investigation of the electrical and optical characteristics of the all-inorganic CsSnI₃ perovskite absorber layer was performed with the Vienna Ab Initio Simulation Package (VASP) using the projector-augmented wave method. The presence of inorganic halide perovskite offers the advantages of enhancing the degradation resistance of the device, reducing the cost of cells, and minimizing the recombination of generated carriers. The simulated standard device using a 1D simulator like solar cell capacitance simulator (SCAPS) version 3308 involves FTO/n-TiO₂/CsSnI₃ Perovskite absorber/Spiro OmeTAD HTL/Au contact layer. The variation in the device design key parameters such as the thickness and defect density of perovskite absorber, hole transport layer and electron transport layer and interfacial defects are examined with their impact on the photovoltaic characteristic parameters. The effect of an increase in operating temperature from 300 K to 400 K on the performance of CsSnI3-based perovskite devices is also investigated. The optimized standard device at room temperature shows the highest PCE of 25.18 % with FF of 75.71 %, Voc of 0.96 V, and Jsc of 34.67 mA/cm².

In fact, there are many causes that show up and influence these cells in a variety of ways. Also, there has been a growing concern over this degradation in the photovoltaic community. One of the main variables deciding PSCs photovoltaic output is defect states. In this research, devices modeling is carried out to analyze the multiple effects of degradation by applying high defect states (HDS) on ideal PSCs, mainly poly(3-hexylthiophene) (P3HT) absorber layer. Besides, a comparative study is conducted between P3HT and other PSCs by a simulation program called Solar Cell Capacitance Simulator (SCAPS). The adjustments to the defect parameters in several absorber layers explain the effect of HDS on the total output properties of PSCs. The performance parameters for HDS, quantum eﬃciency, and energy band were therefore examined. This research attempts to explain the degradation process of PSCs and the causes of their low efficiency. It was found that the defects often affect PSCs performance, but defect states have a little effect on output when the defect level is less than 1014cm-3, which gives similar performance values with P3HT cells when these defects is about 1019cm-3. The high defect states can cause up to 11% relative reduction in conversion efﬁciency of ideal P3HT. In the center of the band gap, defect states become more noxious. This approach is for one of the degradation processes potential of PSCs especially that use fullerene derivative acceptors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=degradation" title="degradation">degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20defect%20states" title=" high defect states"> high defect states</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20solar%20cells" title=" polymer solar cells"> polymer solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=SCAPS-1D" title=" SCAPS-1D"> SCAPS-1D</a> </p> <a href="https://publications.waset.org/abstracts/162233/investigation-of-polymer-solar-cells-degradation-behavior-using-high-defect-states-influence-over-various-polymer-absorber-layers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162233.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">91</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">7</span> Lead-Free Inorganic Cesium Tin-Germanium Triiodide Perovskites for Photovoltaic Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyedeh%20Mozhgan%20Seyed-Talebi">Seyedeh Mozhgan Seyed-Talebi</a>, <a href="https://publications.waset.org/abstracts/search?q=Javad%20Beheshtian"> Javad Beheshtian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The toxicity of lead associated with the lifecycle of perovskite solar cells (PSCs<span dir="RTL">(</span> is a serious concern which may prove to be a major hurdle in the path toward their commercialization<span dir="RTL">.</span> The current proposed lead-free PSCs including Ag(I), Bi(III), Sb(III), Ti(IV), Ge(II), and Sn(II) low-toxicity cations are still plagued with the critical issues of poor stability and low efficiency. This is mainly because of their chemical stability. In the present research, utilization of all inorganic CsSnGeI<sub>3</sub> based materials offers the advantages to enhance resistance of device to degradation, reduce the cost of cells, and minimize the carrier recombination. The presence of inorganic halide perovskite improves the photovoltaic parameters of PCSs via improved surface coverage and stability. The inverted structure of simulated devices using a 1D simulator like solar cell capacitance simulator (SCAPS) version 3308 involves TCOHTL/Perovskite/ETL/Au contact layer. PEDOT:PSS, PCBM, and CsSnGeI<sub>3</sub> used as hole transporting layer (HTL), electron transporting layer (ETL), and perovskite absorber layer in the inverted structure for the first time. The holes are injected from highly stable and air tolerant Sn<sub>0.5</sub>Ge<sub>0.5</sub>I<sub>3</sub> perovskite composition to HTM and electrons from the perovskite to ETL. Simulation results revealed a great dependence of power conversion efficiency (PCE) on the thickness and defect density of perovskite layer. Here the effect of an increase in operating temperature from 300 K to 400 K on the performance of CsSnGeI<sub>3</sub> based perovskite devices is investigated. Comparison between simulated CsSnGeI<sub>3</sub> based PCSs and similar real testified devices with spiro-OMeTAD as HTL showed that the extraction of carriers at the interfaces of perovskite absorber depends on the energy level mismatches between perovskite and HTL/ETL. We believe that optimization results reported here represent a critical avenue for fabricating the stable, low-cost, efficient, and eco-friendly all-inorganic Cs-Sn-Ge based lead-free perovskite devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hole%20transporting%20layer" title="hole transporting layer">hole transporting layer</a>, <a href="https://publications.waset.org/abstracts/search?q=lead-free" title=" lead-free"> lead-free</a>, <a href="https://publications.waset.org/abstracts/search?q=perovskite%20solar%20cell" title=" perovskite solar cell"> perovskite solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=SCAPS-1D" title=" SCAPS-1D"> SCAPS-1D</a>, <a href="https://publications.waset.org/abstracts/search?q=Sn-Ge%20based" title=" Sn-Ge based"> Sn-Ge based</a> </p> <a href="https://publications.waset.org/abstracts/129775/lead-free-inorganic-cesium-tin-germanium-triiodide-perovskites-for-photovoltaic-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129775.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">155</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">6</span> Improved Photo-Active Layer Properties for Efficient Organic Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chahrazed%20Bendenia">Chahrazed Bendenia</a>, <a href="https://publications.waset.org/abstracts/search?q=Souhila%20Bendenia"> Souhila Bendenia</a>, <a href="https://publications.waset.org/abstracts/search?q=Samia%20Moulebhar"> Samia Moulebhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanaa%20Merad-Dib"> Hanaa Merad-Dib</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarra%20Merabet"> Sarra Merabet</a>, <a href="https://publications.waset.org/abstracts/search?q=Sid%20Ahmed%20Khantar"> Sid Ahmed Khantar</a>, <a href="https://publications.waset.org/abstracts/search?q=Baghdad%20Hadri"> Baghdad Hadri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, organic solar cells (OSCs) have become the fundamental concern of researchers thanks to their advantages in terms of flexibility, manufacturing processes and low cost.

In this paper we discuss the sensitivity of light J-V characteristics to various device and material parameters in PIN homo junction solar cells. This work is a numerical simulation of the output parameters of a PIN a-Si:H solar cell under AM1.5 spectrum. These parameters are the short circuit current (Jsc), the open circuit voltage (Voc), the fill factor (FF), the conversion efficiency. The simulation was performed with SCAPS-1D software version 3.3 developed at ELIS in Belgium by Marc Burgelman et al. The obtained results are in agreement with experiment. In addition, the effect of the thickness, doping density, capture cross sections of the gap states and the band microscopic mobilities on the output parameters of the cell are also presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amorphous%20silicon%20p-i-n%20junctions" title="amorphous silicon p-i-n junctions">amorphous silicon p-i-n junctions</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film" title=" thin film"> thin film</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cells" title=" solar cells"> solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity" title=" sensitivity"> sensitivity</a> </p> <a href="https://publications.waset.org/abstracts/21840/sensitivity-studies-for-a-pin-homojunction-a-sih-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21840.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">521</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">2</span> Mechanism of Charge Transport in the Interface of CsSnI₃-FASnI₃ Perovskite Based Solar Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyedeh%20Mozhgan%20Seyed-Talebi">Seyedeh Mozhgan Seyed-Talebi</a>, <a href="https://publications.waset.org/abstracts/search?q=Weng-Kent%20Chan"> Weng-Kent Chan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsin-Yi%20Tiffany%20Chen"> Hsin-Yi Tiffany Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lead-free perovskite photovoltaic (PV) technology employing non-toxic tin halide perovskite absorbers is pivotal for advancing perovskite solar cell (PSC) commercialization. Despite challenges posed by perovskite sensitivity to oxygen and humidity, our study utilizes DFT calculations using VASP and NanoDCAL software and SCAPS-1D simulations to elucidate the charge transport mechanism at the interface of CsSnI₃-FASnI₃ heterojunction. Results reveal how inherent electric fields facilitate efficient carrier transport, reducing recombination losses. We predict optimized power conversion efficiencies (PCEs) and highlight the potential of CsSnI3-FASnI3 heterojunctions for cost-effective and efficient charge transport layer-free (CTLF) photovoltaic devices. Our study provides insights into the future direction of recognizing more efficient, nontoxic heterojunction perovskite devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=charge%20transport%20layer%20free" title="charge transport layer free">charge transport layer free</a>, <a href="https://publications.waset.org/abstracts/search?q=CsSnI%E2%82%83-FASnI%E2%82%83%20heterojunction" title=" CsSnI₃-FASnI₃ heterojunction"> CsSnI₃-FASnI₃ heterojunction</a>, <a href="https://publications.waset.org/abstracts/search?q=lead-free%20perovskite%20solar%20cell" title=" lead-free perovskite solar cell"> lead-free perovskite solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=tin%20halide%20perovskite." title=" tin halide perovskite."> tin halide perovskite.</a>, <a href="https://publications.waset.org/abstracts/search?q=Charge%20transport%20layer%20free" title=" Charge transport layer free"> Charge transport layer free</a> </p> <a href="https://publications.waset.org/abstracts/186055/mechanism-of-charge-transport-in-the-interface-of-cssni3-fasni3-perovskite-based-solar-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186055.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">45</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">1</span> Device Modelling and Analysis of Eco-friendly Inverted Solar Cell Structure Using Valency Ordered Inorganic Double Perovskite Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sindhu%20S%20Nair">Sindhu S Nair</a>, <a href="https://publications.waset.org/abstracts/search?q=Atul%20Thakur"> Atul Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Preeti%20Thakur"> Preeti Thakur</a>, <a href="https://publications.waset.org/abstracts/search?q=Trukhanov%20Alex"> Trukhanov Alex</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Perovskite-based absorbing materials that are organic, inorganic, or hybrid have gained interest as an appealing candidate for the development of solar cell devices. Lead-based perovskites are among the most promising materials, but their application is plagued with toxicity and stability concerns. Most of the perovskite solar cell consists of conventional (n-i-p) structure with organic or inorganic charge transport materials. The commercial application of such device is limited due to higher J-V hysteresis and the need for high temperature during fabrication. This numerical analysis primarily directs to investigate the performance of various inorganic lead-free valency ordered double perovskite absorber materials and to develop an inverted perovskite solar cell device structure. Simulation efforts using SCAPS-1D was carried out with various organic and inorganic charge transport materials with absorber layer materials, and their performance has been evaluated for various factors of thickness, absorber thickness, absorber defect density, and interface defect density to achieve the optimized structure. <p class="card-text"><strong>Keywords:</strong> <a
