The perovskite solar cells (PSCs) have been extensively interested and its performance has rapidly increased up to 24.2 %. Layer thickness and charge mobility are crucial for high-performance perovskite solar cells. In this paper, we study the effect of layer thickness and charge mobilities on some parameters in perovskite solar cell based on structure of FTO/TiO x /SnO 2 /FAIMABrPbI 2 PbBr 2 /Spiro-OMeTAD/Ag by using the GPVDM (General-purpose Photovoltaic Device Model) software. The simulation results show that the best optimized power conversion efficiency of 23.88 % can be obtained. The optimal layer thickness in the simulation of TiO x , SnO 2 , FAIMABrPbI 2 PbBr 2 , Spiro-OMeTAD are 50 nm, 30 nm, 400 nm, 30 nm, respectively. The optimal electron and hole mobilities of photoactive layer are 2×10 -5 m 2 V -1 s -1 and 2×10 -6 m 2 V -1 s -1 , respectively. Comparative study of simulation and experiment are observed, that performance of 15.93 % of efficiency can be experimentally achieved, however the model of this solar cell is observed 18.43 % of efficiency by simulation.
