“…The graph illustrates the CdTe solar device's electrical performance. When acceptor defect density is varied between 1 × 10 14 and 1 × 10 20 cm −3 , [ 64 ] the solar cell's efficiency decreases from 25.07% to 9.49%. The major change in efficiency occurs when the defect concentration exceeds 1 × 10 16 cm −3 .…”

This article discusses the numerical analysis of heterojunction photovoltaic cells based on cadmium telluride (CdTe) using the SCAPS‐1D software. A novel glass/FTO/SnO2/CdS/interdiffusion/CdTe/SnS2/Se photovoltaic cell design is proposed for investigation. Additionally, the effect of thickness variation in the p‐type CdTe film, thickness variation in the interdiffusion layer, defect density in the CdTe film, defect density in the interdiffusion layer, and acceptor concentration in the CdTe layer is studied in order to improve the photovoltaic cell's efficiency. The study determines an optimal thickness of 1 and 0.6 μm for the CdTe and interdiffusion layers, respectively, a defect density of 1 × 1014 cm−3 for the CdTe film and interdiffusion region, an interface defect density of 1 × 1010 cm−3 between CdTe/interdiffusion, SnS2/CdTe, and CdS/interdiffusion, and an acceptor concentration value of 8.5 × 1015 cm−3. The optimized CdTe photovoltaic cell structure with current density (Jsc) = 30.003 mA cm−2, open‐circuit voltage (Voc) = 1.061 V, and fill factor (FF) = 88.10% achieves a 28.07% efficiency, compared to the baseline CdTe photovoltaic cell structure with a 23.01% efficiency.

“…The SCAPS software was utilized for the simulation (3.3.09). This one dimensional solar cell simulator was created at the University of Gent in Belgium [30][31][32][33]. The simulated NFA-BHJ-OSC is con gured as substrate/MoO 3 doped CNT/PEDOT: PSS/PBDB-T/ITIC-OE/PFN-Br/Ag.…”

“…Due to the decrease in resistivity, the ll factor parameter increases. The overall resistivity of CNT is reduced by p-type doping in two ways: i) the free carrier concentration per nanotube is enhanced, and ii) the intra nanotube junction resistance is reduced because carriers can ow more freely between metallic and semiconducting states [30]. As a result of the higher J sc and FF, PCE improves to 22.71%.…”

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.

“…Different materials such as organic polymers [ 11 , 12 ], silicon [ 13 , 14 ], CIGS [ 15 , 16 ], and CdS/CdTe [ 17 , 18 ] have been investigated numerically to improve the device performance to obtain high conversion efficiency. Moreover, numerical modeling and simulation are always encouraged to estimate the parameters before moving towards the fabrication side.…”

This paper reports numerical modeling of perovskite solar cell which has been knotted with Distributed Bragg Reflector pairs to extract high energy efficiency. The geometry of the proposed cells is simulated with three different kinds of perovskite materials including CH3NH3PbI3, CH3NH3PbBr3, and CH3NH3SnI3. The toxic perovskite material based on Lead iodide and lead bromide appears to be more efficient as compared to non-toxic perovskite material. The executed simulated photovoltaic parameters with the highest efficient structure are open circuit voltage = 1.409 (V), short circuit current density = 24.09 mA/cm2, fill factor = 86.18%, and efficiency = 24.38%. Moreover, a comparison of the current study with different kinds of structures has been made and surprisingly our novel geometry holds enhanced performance parameters that are featured with back reflector pairs (Si/SiO2). The applied numerical approach and presented designing effort of geometry are beneficial to obtain results that have the potential to address problems with less efficient thin-film solar cells.
