Ion Exchange-Enabled High-Speed Self-Power Photodetector Arrays Based on Large-Scale Monocrystalline Perovskite Films
Cesium lead halide perovskites exhibit valuable electrical and optical properties and have potential applications in photodetectors. In this study, large-area monocrystalline CsPbBr3 films were grown via chemical vapor deposition and subsequently transformed into CsPb(Br0.5I0.5)3 thin films via ion exchange. The results demonstrate that the substrate temperature and precursor reaction completeness significantly affect the growth of monocrystalline CsPbBr3 films. Furthermore, large-area self-powered CsPb(Br0.5I0.5)3 photodetectors with a high switch ratio (>103) and fast response speed (108 μs/105 μs) were developed. Additionally, a CsPb(Br0.5I0.5)3 image sensor array capable of high-resolution pattern identification was fabricated. This work represents a substantial step toward synthesizing large-area, high-quality monocrystalline CsPbBr3 and ion exchange films for potential optoelectronics applications.
