Single crystals of methylammonium lead trihalide perovskites have been widely applied in the research of next-generation photodetectors due to their remarkable light-harvesting properties, low trap density, and good carrier transport ability. Herein, the presented work demonstrates the high-quality and millimeter-scale single crystals CH3NH3PbBr3 and CH3NH3PbI3 perovskite-based planar photodetectors modified by the inverse temperature crystallization technique. The highest photoresponsivity of CH3NH3PbBr3 photodetector can reach ∼111 A W−1 under the visible illumination of 520 nm light and the highest photoresponsivity of CH3NH3PbI3 photodetector can reach ∼568 A W−1 under the infrared illumination of 895 nm light. The photodetectors also demonstrate high on/off ratio and fast response speed. It implies that CH3NH3PbBr3 and CH3NH3PbI3 single crystals based photodetectors reveal great attention for the applications of visible–infrared photodetection.
