Effect of halide ion in the perovskite on perovskite solar cell performances

Abstract

In this paper, a p-i-n perovskite solar cell was studied using Solar Cell Capacitance Simulator (SCAPS). A perovskite solar cell with MAPbI 3 and a perovskite solar cell with MAPbBr 3 as the light-absorbing materials have been simulated and compared the effect of the halide ion on solar cell performances. The efficiency of MAPbI 3 and MAPbBr 3 were reached 16.8% and 5.14% respectively. Also, the thickness of each MAPbI 3 and MAPbBr 3 was varied from 0.1 μm to 1.2 μm and the best results were observed at 0.5 μm and 0.4 μm thickness of MAPbI 3 and MAPbBr 3 films, respectively. A considerable effect of halide ions on perovskite solar cell performances can be attributed to the variation of light absorption with the halide ions.
