Autonomous Reconstitution of Fractured Hybrid Perovskite Single Crystals (Adv. Mater. 19/2022)

Hybrid Organic–Inorganic Perovskites In article number 2109374, Luca Catalano, Panče Naumov, and co-workers address the poor mechanical robustness of bulk hybrid organic–inorganic perovskite (HOIP) crystals by demonstrating that broken centimeter-size single crystals of a typical HOIP, MAPbI3, can readily self-repair under mild compressive forces at ambient temperature. The self-healed crystals show an impressive recovery of their mechanical and optoelectronic properties.
