Abstract:
Modifying the interfaces of CH3NH3PbI3 with TiO2 and hole transport layers using two different types of thiols leads to enhanced performance and stability of perovskite solar cells. The incorporation of HOOC-Ph-SH at the TiO2/perovskite interface facilitates electron transfer from perovskite to TiO2 and also alters the morphology of perovskite crystal growth to increase the power conversion efficiency. The modification of pentafluorobenzenethiol at the perovskite/hole transport layer interface improves the stability.
