Exceptionally Stable CH(3)NH(3)PbI(3) Films in Moderate Humid Environmental Condition

An unprecedentedly stable CH(3)NH(3)PbI(3) film synthesized by a modified chemical vapor transport method is demonstrated. The results show that the crystal structure, light absorption, and device efficiency do not degrade after storing for 100 d in air with 40% relative humidity, while the conventi...

Sumario:An unprecedentedly stable CH(3)NH(3)PbI(3) film synthesized by a modified chemical vapor transport method is demonstrated. The results show that the crystal structure, light absorption, and device efficiency do not degrade after storing for 100 d in air with 40% relative humidity, while the conventional solution‐processed perovskites are usually stable for less than 20 d in similar conditions.
