The preparation of WS 2 nanosheets and their application for hole transport layer in perovskite solar cells are investigated in this work. WS 2 nanosheets were prepared by liquid phase supersonic exfoliation method. Then by using solution spin-coating method the WS 2 nanosheets thin films were introduced as the hole transport layer (HTL) material in the planar heterojunction perovskite solar cells. The results indicate when the concentration of WS 2 nanosheet solution is 1 mg/mL, the thickness of the WS 2 nanosheet thin films is suitable for the application to the hole transport layer, and the perovskite active layers grown on them have high film quality and good crystallinity. Finally a photoelectric conversion efficiency of 6.3% is obtained. In this study, we demonstrate an effective new use of WS 2 nanosheets HTL in the perovskite solar cells. 二硫化钨纳米片 液相超声剥离法 钙钛矿太阳能电池 空穴传输层 WS 2 nanosheets liquid phase supersonic exfoliation perovskite solar cells hole transport layer YAN J F,SAUNDERS B R.
