Abstract

Hybrid organic–inorganic perovskites have attracted intensive interest as light absorbing materials in solid-state solar cells. Herein, we demonstrate a high-performance CH3NH3PbI3-based perovskite photodetector constructed on the flexible indium tin oxide (ITO) coated substrate even after 200 bending cycles. The as-fabricated devices show high responsivity, broad spectrum response from ultraviolet to whole visible light, long-term stability, and high on-off ratio. Particularly, atomic layer deposition technique was used to deposit the ultrathin Al2O3 film on devices, functioning as a protection layer to effectively enhance the stability and durability of perovskite photodetectors. The first all-perovskite self-powered nanosystem was successfully assembled by integrating a perovskite solar cell with a perovskite photodetector. Driven by the perovskite solar cell, the photodetector exhibits fast and stable response to illuminated light at a low working voltage less than 1.0 V. This stable integrated nanosystem has promising applications in which photodetectors can work in harsh environments without external power sources.
