Abstract

Solar cells consisting of perovskites materials have shown great interest because of their low cost and high-power conversion efficiency (PCE). But still there are some issues such as limited absorption, hysteresis and device instability. In the present work we have simulated the formamidinium lead tri-iodide (FAPbI3) based perovskite solar cell and the effect of incorporation of SnO2 Electron transport layer (ETL) on the power conversion efficiency of solar cell has been investigated. The device without SnO2 layer shows low efficiency of 21.71 % at 267 Kelvin. But after incorporation of ETL, the device obtained a PCE of 24 % at 267 Kelvin. The effect of thickness of hole transport layer (HTL), ETL and doping density on the PCE has been analysed using Solar cell capacitance simulator (SCAPS-1D) software tool. This study shows that FAPbI3 may be a promising material for enhancing the PCE of perovskite solar cells (PSCs).
