摘要

An unfortunate and fortunate discovery is that metal halide perovskites are not completely defect tolerant,while fullerenes,which are inexpensive and broadly applied in organic solar cells,have a considerable passivation effect toward the surface defects ofperovskite materials [1].The improvement ofperovskite efficiency and stability in the last five years has shown the importance of passivating interfacial charge traps to reduce charge carrier recombination and to slow down the degradation of perovskites [2].
