Since the rapid development of perovskites-based photovoltaics and LED, innovative and disruptive applications for light detection also emerged. Perovskites combine effective light absorption and high carrier mobility, which provides promising potential for exploiting sensitive and fast photodetectors targeted for image sensing, optical communication, environmental monitoring, etc. Currently, hybrid and all-inorganic halide perovskites with controlled morphologies and bulk single crystals have shown key figure-of-merit features in terms of their responsivity, detectivity, noise equivalent power, linear dynamic range, and response speed. The sensing region has been covered from UV to gamma photons, based on two- or three-terminal device architectures. Here, we offer a comprehensive overview of the recent progress of perovskite-based photodetectors, focusing on versatile compositions, structures, and morphologies, and diverse device architectures toward the superior performance metrics. |
