摘要：

A new aliphatic fluorinated amphiphilic additive is added to CH3NH3PbI3 perovskite to tune the morphology and enhance the environmental stability without sacrificing the performance of the devices. Judicious screening of the perovskite precursor solution realizes a power conversion efficiency of 18.0% for mesoporous perovskite solar cells as a result of improved surface coverage. A slower degradation in ambient air is observed with this modified perovskite. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
