A crown ether named dibenzo-18-crown-6 is introduced to modify the interface between the perovskite and the electron transport layers. Due to its unique electron cavity and electron-rich system, it effectively passivates defects and simultaneously suppresses cation migration, thereby achieving a high power conversion efficiency of 24.19% with excellent stability.
