Abstract

A thermo-cleavable fullerene derivative was used as an interfacial engineering material in planar perovskite solar cells. The modified TiO2 surface shows exceptional resistance against polar solvent washing and the perovskite film grown on it was of high quality with less pinholes. Consequently, high performance devices without hysteresis have been achieved.
