Abstract
Applications involving image sensors, computer vision, and optical communications all require adjustable spectral narrowband photodetectors. In recent years, because of their excellent optoelectronic characteristics, metal halide perovskites have drawn a great deal of interest. Bearing these properties, narrowband photodetectors using perovskites as either active or other functional layers have demonstrated excellent performance, covering both wide and tunable spectral range. In this review, latest advancements in narrowband perovskite photodetectors are outlined, focusing on fundamental physics, implemented strategies, and new opportunities for the realization of narrowband detection. The device physics of photodetectors are comprehensively reviewed followed by the key conventional implementation strategies for narrowband detection based on traditional semiconductor materials and solution-processable materials (organics, quantum dots). After brief description of the material and morphological properties of perovskites, emphasis is put on the most recent developments of the strategies for narrowband perovskite photodetectors. While clarifying several narrowband detection strategies, innovative device architectures, respective applications, and existing limitations are analyzed in detail along with the discussion of the feasibility of applying the traditional strategies to perovskite materials for narrow spectral detection. Finally, considering both the perspective and the current challenges, an outlook of the future development in this rapidly evolving field of perovskite narrowband photodetection is presented for a wider scope of theoretical research and promising technological developments.
