摘要：
A typical p-type semiconductor material CuPc was introduced as hole transport layer in inverted planar solar cell structure,CuPc films were prepared by thermal evaporation deposition,and the device was prepared under low temperature conditions.The effects of different CuPc films thickness on the properties of perovskite solar cells were optimized,and the properties of cells and CuPc films were analyzed by current-voltage measurement,scanning electron microscopy,atomic force microscopy and X-ray diffraction.Research results show that the thermal evaporation deposited CuPc exhibits good flatness and coverage,and when the thickness was 10 nm,the device achieves the highest power conversion efficiency of 15.37% on the rigid substrate and 12.66% on the flexible substrate.This device has the advantages of simple preparation process,low cost and high reproducibility,which provides a reference of further preparation of large-area,high-efficiency and flexible perovskite solar cells. © 2019, Editorial Board of Journal of Huazhong University of Science and Technology.
