A promising photodetector based on CH 3 NH 3 PbI 3 single crystal under visible light and X‐ray irradiation is reported. The CH 3 NH 3 PbI 3 crystal grown by inverse temperature crystallization acts as the absorber material directly converting visible light and the impinging X‐ray photons to electron hole pairs, respectively. The underlying photoelectric response mechanism behind the observation under visible light and X‐ray irradiation is carefully discussed. Remarkably, the perovskite detectors demonstrate a good air‐exposure stability for more than 2 months with encapsulation. The results demonstrate that the CH 3 NH 3 PbI 3 single crystal has a great potential for application in the visible light and X‐ray detection.
