主　　题：instability perovskite ammonium 

摘      要：Organo-lead halide perovskites(OHPs) possess superior optoelectronic properties and have achieved an amazing certified power conversion efficiency(PCE) of 25.5% in perovskite solar cells(PSCs)[1]. Recent studies revealed that the organic cations such as methylammonium(MA^(+)) and formamidinium(FA^(+)) and anions with weak electronegativity such as I^(-) in OHPs were causing instability.
