Abstract
Abstract The feasibility of CuI and C60 as hole transport layer and electron transport layer in the perovskite solar cell is tested by using the software Solar Cell Capacitance Simulator (SCAPS). It is found that the thicknesses of the absorption layer, electron transport layer and hole transport layer, and the Interface Density of Defect State of their interface have a key influence on the efficiency of the perovskite solar cells. After optimization, the efficiency was as twice as that before, 22.70% to 11.62%, and the fill factor can still be at a high value, 76%.
