Nowadays, lead free eco-friendly perovskite nonmaterial is trending for photovoltaic devices application. In this study, proposed device structure of perovskite solar cell is ITO/SWCNT/CH3NH3SnI3/Cz-P/Pd. In this device SWCNT, CH3NH3SnI3,Cz-P, and Pd have been utilized as ETL, absorber layer, HTL and back contact material respectively. The performance parameter of perovskite solar cell like open circuit voltage, current density, fill factor and power conversion efficiency have been optimised. Device performance mainly depends upon the thickness, total defect density, donor defect density and bandgap of the perovskite absorber layer. Additionally, the work-function, series and shunt resistance of the whole device have also been optimised. The optimised result of proposed perovskite solar cell with open circuit voltage is 0.998 V, current density is 38.77 mA/cm2, fill factor is 77.46% and power conversion efficiency is 29.99% obtained. These results have been calculated through SCAPS-1D simulator. This device opens the door for researchers to develop low cost environment friendly solar cell. |
