Recent years have witnessed skyrocketing research achievements in organic–inorganic hybrid lead halide perovskites (OIHPs) in the photovoltaic field. In addition to photovoltaics, more and more studies have focused on OIHPs‐based photodetectors in the past two years, due to the remarkable optoelectronic properties of OIHPs. This article summarizes the latest progress in this research field. To begin with, the factors influencing the performance of photodetectors are discussed, including both internal and external factors. In particular, the channel width and the incident power intensities should be taken into account to precisely and objectively evaluate and compare the output performance of different photodetectors. Next, photodetectors fabricated on single‐component perovskites in terms of different micromorphologies are discussed, namely, 3D thin‐film and single crystalline, 2D nanoplates, 1D nanowires, and 0D nanocrystals, respectively. Then, bilayer structured perovskite‐based photodetectors incorporating inorganic and organic semiconductors are discussed to improve the optoelectronic performance of their pristine counterparts. Additionally, flexible OIHPs‐based photodetectors are highlighted. Finally, a brief conclusion and outlook is given on the progress and challenges in the field of perovskites‐based photodetectors.

基于有机-无机杂化卤化铅钙钛矿的光电探测器
近年来，有机-无机杂化卤化铅钙钛矿（OIHPs）在光伏领域的研究成果突飞猛进。除了光伏发电之外，由于 OIHP 卓越的光电特性，过去两年越来越多的研究集中在基于 OIHP 的光电探测器上。本文总结了该研究领域的最新进展。首先，讨论影响光电探测器性能的因素，包括内部因素和外部因素。特别是，应考虑通道宽度和入射功率强度，以准确、客观地评估和比较不同光电探测器的输出性能。接下来，讨论了在不同微形貌的单组分钙钛矿上制造的光电探测器，分别是 3D 薄膜和单晶、2D 纳米板、1D 纳米线和 0D 纳米晶体。然后，讨论了结合无机和有机半导体的双层结构钙钛矿光电探测器，以提高其原始对应物的光电性能。此外，还重点介绍了基于 OIHP 的灵活光电探测器。最后，对钙钛矿光电探测器领域的进展和挑战进行了简要的总结和展望。
