Abstract

Abstract : In article number1900219, Donghwa Lee, Jooho Moon, and co‐workers develop an approach to stabilize α ‐CsPbI3 perovskite through strain engineering, whereby CsPbI3 perovskite is confined by a vertically aligned nanoporous template. By imposing a strain on the perovskite lattice, the ultra‐stable black α ‐CsPbI3 with its desirable optoelectrical properties is obtained. This universally applicable template‐based stabilization strategy provides in‐depth insights on the strain‐mediated phase transition mechanism in all‐inorganic perovskite.
