Recent Progress on Perovskite Photodetectors for Narrowband Detection

Narrowband detection is of urgent demand in many fields, such as machine vision, biofluorescence imaging, artificial intelligence, flame, or gas molecule monitoring. However, the restricted recognition area and complex integration hinder development narrowband photodetectors. Due to excellent photoconversion efficiency, metal halide perovskites are emerging a new star field high-performance In recent years, soaring attention has been focused on photodetectors using absorbing layers, owing performance tunable absorption peaks covering wide optical range. Herein, this review latest research progress perovskite photodetectors, emphasizing strategy for from novel functional applications existing problems. The study looking forward elucidating different internal mechanisms detection, providing unique insights into challenges area, giving rise prosperity detection.
