Long-term operational stability is the foremost issue delaying the commercialization of perovskite solar cells (PSCs). Here we demonstrate an in-situ cross-linking strategy for operationally stable inverted MAPbI 3 PSCs through the incorporation of a cross-linkable organic small molecule additive tr...
