“…Usually, J sc is weaker than J v [47], so the value ln J sc =J v ð Þalso becomes almost a constant which makes the V oc also constant, as shown in Figure 2(b). The FF is heavily affected by the internal electric field [48] when the thickness increases, the internal electric field reduces and gets deformed, making the FF reduce with an increase in thickness [46,48].…”

Thin-film-based photovoltaics offer affordable solar panels (high energy output per unit cost). Various materials have been used for thin-film solar cells, and still, new materials are being tested. In this work, the overall performance of GeSe is enhanced theoretically from a generic solar structure to a configuration that yields a whopping 33.12% efficiency along with an open circuit voltage of 1.04 V by optimizing various active layers using solar cell capacitance simulator SCAPS. The results have been explained most simply, utilizing the physics behind introducing hole transport layers in solar cells. The work also shows how certain contradictions in parameter values in the literature of GeSe can influence the cell’s performance. The result shows why the substrate structure is better than the superstrate structure. Most of the reported results are on superstrate structure, which might have caused poor performance in previously experimentally produced GeSe solar cells.

The utilization of perovskite and crystalline-silicon (c-Si) light absorbers in multijunction solar cells presents an exciting opportunity to surpass the efficiency limit of the industry's leading single-junction c-Si solar cells. In this work, we used the Solar Cell Capacitance Simulator (SCAPS-1D) to simulate a monolithic tandem junction solar cell. The solar cell consists of two types of materials: low bandgap and high bandgap. These are layers of perovskites and Si, divided by a window layer of zinc oxide (ZnO), a buffer layer of cadmium sulfide (CdS), a recombination layer of Spiro-MeOTAD/silicon, and a heavily doped back surface field layer formed from n++Si to prevent recombination at the back surface. The impact of di fferent series and shunt resistances, as well as perovskite layer thickness and bandgap, on solar cells' photovoltaic performance has been investigated.

The most common transparent conducting electrode, ITO, is delicate and prone to shattering under mechanical stress, which lowers the device's performance on flexible plastic substrates. Because of their exceptional optical transparency, low sheet resistance, and great mobility, carbon nanotubes have garnered a lot of interest as a Transparent Conductive electrode in organic solar cells. Molybdenum Trioxide (MoO3) doping of carbon nanotube Transparent Conductive electrodes makes p-doping, good energy-level alignment, and improved hole transport possible. In the present study, the performance of Non-Fullerene ITIC-OE Acceptor Organic Solar Cells with a transparent electrode fabricated from Carbon Nanotubes doped with Molybdenum trioxide (MoO3) is simulated using SCAPS 1-D. The optimized PCE of 24.94 %, Fill Factor (FF) of 74.02 %, Jsc of 35.32 mA/cm2 and Voc of 0.9539 V are shown in the current work by varying the band gap of MoO3 doped CNTs. Also, upgrading the simulated cell's Electron transport Layer (ETL) with SnO2, TiO2, and ZnO yields an optimized result with TiO2 ETL, having PCE of 25.71%, FF of 76.30%, Jsc of 35.32 mA/cm2, and Voc of 0.9539 V. These results demonstrated the possibilities for ITIC-OE acceptor Organic Solar Cells with Transparent Conductive Electrodes made of carbon nanotubes to advance device performance in the near future.
