Optimal design and photovoltaic performance of eco friendly, stable and efficient perovskite solar cell

In this study, we have investigated a lead-free perovskite solar cell with Two-Dimensional (2-D) electron and hole transport materials using device simulation software. We have analyzed the characteristics of the solar cell and quantum efficiency at the illumination of light and measured the output performance parameters. We have varied device parameters, such as absorber thickness, absorber doping concentration, and defect density in the absorber layer, to get the optimized values of the solar cell module. We have also considered the effect of interface layer defect density and temperature variation factors. Simulation results showcase a short circuit current density (Jsc) of 27.3 mA/cm2, open-circuit voltage (Voc) of 0.96 V, fill-factor (FF) of 87.62%, and power conversion efficiency (PCE) of 22.17%. The high quantum efficiency (QE) of 98% in the visible region is due to the material's high absorbance with our proposed perovskite solar cell (PSC). Finally, we compared our proposed PSC with other solar cells to state the efficiency of the perovskite material used in our cell module. This work provides a route towards the development of eco-friendly and stable perovskite solar cells.
