Abstract
Organic photodetectors (OPDs) are promising for applications in flexible electronics due to their advantages of excellent photodetection performance, cost‐effective solution‐fabrication capability, flexible device design, and adaptivity to manufacturability. This review outlines the recent advances in the development of high‐performance OPDs and their applications in flexible electronics. The approaches to developing different noise reduction methods, filter‐free spectral selective detection, flexible OPDs, and scale‐up production of flexible OPDs through solution‐fabrication processes are discussed. Applications of the OPD technology ultimately result in the materialization of wearable units, flexible and compact information sensors at commercially viable costs, including wearable health self‐monitoring devices, flexible optical communication systems, and flexible large‐area image sensors.
