Large and Ultrastable All‐Inorganic CsPbBr3 Monocrystalline Films: Low‐Temperature Growth and Application for High‐Performance Photodetectors
Source abstract
Abstract
Abstract Stability is a key problem that hinders the practical application of lead halide perovskite. Therefore, all‐inorganic perovskite CsPbX3 monocrystalline films are urgently needed to fabricate photoelectric devices. Herein, a low‐temperature and substrate‐independent growth method is demonstrated to grow millimeter‐level inorganic perovskite monocrystalline thin films. These films present good optical and electrical properties comparable to bulk ones. What is more, they exhibit excellent long‐term stability toward humidity and thermal treatment. The as‐grown CsPbBr3 monocrystalline films are then fabricated into photodetectors with high photodetection performance. These results demonstrate that the CsPbBr3 monocrystalline films have potential in fabricating high‐performance optoelectronic devices.
