Recent Progress on Highly Sensitive Perovskite Photodetectors


Perovskite photodetectors (PPDs), combining the advantages of perovskite semiconductor materials with superior optical and electronic properties and solution-processed manufacturing, have emerged as a new class of revolutionary optoelectronic devices promising for various practical applications. Encouraged by the development of various solution-synthesis and film-deposition techniques for controlling morphology and composition of perovskite materials with interesting optoelectronic properties, more and more attention is focused on the research of developing high performance PPDs. In this review, the recent progresses on emerging PPDs are comprehensively summarized from the perspective of device physics and material science. The strategy of extending spectral response range of PPDs and improving the performance of devices are investigated. The methods of realizing the narrowband photodetectors are also discussed, and the filter-free and self-filter narrowband PPDs are achieved based on the concept of charge collection narrowing. Meanwhile, the promising future directions in this research field are proposed and discussed, including multifunctional PPDs, perovskite organic hybrid photodetectors, flexible and transparent PPDs, self-powered PPDs, and photodetector systems and arrays. This review can provide valuable insights into current status of highly sensitive PPDs and spur new structure and device designs to further enhance photo-detection performance and meet the need of versatility in practical application.
