Effect of Halide Ion in the Perovskite on Perovskite Solar Cell Performances

摘要

In this paper, a p-i-n perovskite solar cell was studied using Solar Cell Capacitance Simulator (SCAPS). A perovskite solar cell with MAPbI3 and a perovskite solar cell with MAPbBr3 as the light-absorbing materials have been simulated and compared the effect of the halide ion on solar cell performances. The efficiency of MAPbI3 and MAPbBr3 were reached 16.8% and 5.14% respectively. Also, the thickness of each MAPbI3 and MAPbBr3 was varied from $0.1 mumathrm{m}$ to $1.2 mumathrm{m}$ and the best results were observed at $0.5 mumathrm{m}$ and $0.4 mumathrm{m}$ thickness of MAPbI3 and MAPbBr3 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.
