摘要：
Electronic devices comprising a first layer, said first layer comprising a perovskite material; and a coating layer disposed on a surface of said first layer; wherein said coating layer comprises a coating oxysalt. Also provided herein are perovskite materials comprising: a coating layer on at least a portion of a surface of said perovskite material; wherein said coating layer comprises a coating oxysalt. Further provided herein are methods for forming a coating layer on a surface of a perovskite material comprising steps of: exposing said surface to a fluid having a precursor oxysalt dissolved therein such that said coating layer forms on said surface via a chemical reaction between said perovskite material and said precursor oxysalt; wherein said coating layer comprises a coating oxysalt.
