摘要	Recent investigations indicate that the performance of organic-inorganic perovskite optoelectronic devices can be improved by combining the perovskites and the inorganic materials. However, very few studies have focused on the investigation of perovskites/inorganic semiconductor hybrid UV photodetectors and their detailed performance-enhancement mechanism is still not very clear. In this work, a CH3NH3PbCl3/ZnO UV photodetector has been first demonstrated and investigated. Both the photoresponsivity and response speed of the hybrid device are higher than those of pure CH3NH3PbCl3 and ZnO devices. The photoluminescence and transient absorption spectra indicate that the photoinduced electron transfer between CH3NH3PbCl3 and ZnO should be responsible for the performance enhancement of the hybrid device. In addition, the high crystal quality of CH3NH3PbCl3 on ZnO film is another important reason for the excellent UV detection performance. Our findings in this work provide new insights into the intrinsic photophysics essential for perovskite optoelectronic devices.
