P‐92: Low‐Power Perovskite Photodetector Based on ZnO/CsPbBr 3 /TFB Heterojunction

A photodetector based on ZnO/CsPbBr 3 /TFB heterojunction has been fabricated. The effect of ZnO film thickness on device performance has been discussed. The device can be operated at 0V and shows the maximum performance with detectivity of 2x10 12 Jones and on/off ratio of 2.4x10 5 at ‐0.62V, showing a low‐power characteristic.
