摘要：

Two pseudohalide thiocyanate ions (SCN-) have been used to replace two iodides in CH3NH3PbI3, and the resulting perovskite material was used as the active material in solar cells. In accelerated stability tests, the CH3NH3Pb(SCN)(2)I perovskite films were shown to be superior to the conventional CH3NH3PbI3 films as no significant degradation was observed after the film had been exposed to air with a relative humidity of 95% for over four hours, whereas CH3NH3PbI3 films degraded in less than 1.5hours. Solar cells based on CH3NH3Pb(SCN)(2)I thin films exhibited an efficiency of 8.3%, which is comparable to that of CH3NH3PbI3 based cells fabricated in the same way.
