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...
The outstanding performance and facile processability turn hybrid organic–inorganic perovskites into one of the most sought‐after classes of semiconducting materials for optoelectronics. Yet, their translation into real‐world applications necessitates that challenges with their chemical stability and poor mechanical robustness are first addressed. Here, centimeter‐size single crystals of methylammoniumlead(II)...
