Solution-Processable Methyl Ammonium Lead Iodide Single Crystal Photodetectors for Visible Light and X-Ray
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.
