Investigation of electrical properties of CH3NH3Sn(I1-xClx)3 perovskite solar cell by SCAPS-1D simulation

Abstract

In this research, we developed a tin-based eco-friendly CH3NH3Sn(I1-xClx)3 perovskite solar cell to simulate the architecture FTO/TiO2/CH3NH3Sn(I1-xClx)3/Cu2O by using the SCAPS-1D. We have studied the effect of the performance of solar cells by varying thickness, band gap energy, doping acceptor density, and total defect density of absorber layer-CH3NH3Sn(I1-xClx)3 through the software tool. At first, we simulate the device and find the performance of electrical properties such as efficiency, based on the parameters that are taken from the previous research paper. Later we vary only on the absorber layer parameters mentioned above, to get the optimum results of the designed solar cell. The efficiency for the plugging parameters value and after applying the parameter obtained optimum value jumped from 27.83% to 39.28%. After optimizing all the properties, the efficiency has been enhanced by about 11.45%.
