Abstract

A multifunctional group molecule, namely MATC, was first introduced into a Cs/FA-based perovskite used as an additive. An impressive PCE of 21.51% was achieved for the inverted PSCs with reduced defect states and improved perovskite film quality. Moreover, MATC passivation considerably enhanced the stability of the PSC devices.
