Abstract
The present invention provides methods for increasing stability and efficiency of organic perovskite materials for use in various electronic devices. In particular, methods of the invention use a non-peripheral substituted phthalocyanine for passivating defects in organic perovskite materials, thereby increasing its stability and efficiency relative to the same material in the absence of said non-peripheral substituted phthalocyanine.
