Defect-mediated carrier recombination at the interfaces between perovskite and neighboring charge transport layers limits the efficiency of most state-of-the-art perovskite solar cells. Passivation of interfacial defects is thus essential for attaining cell efficiencies close to the theoretical limit. In this work, a novel double-sided passivation of 3D perovskite films is demonstrated with thin surface layers of bulky organic cation–based halide compound forming 2D layered perovskite.
