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.
