Abstract

Abstract : Organic Photodetectors Organic photodetectors (OPDs) for sensitive detection of a weak light can be achieved by suppression of dark current density of photo active layers. In article number 2108026, Seung‐Hoon Lee, Changjin Lee, Sung Cheol Yoon, and co‐workers suggest a simple but effective method to reduce the dark current density of OPDs by introducing F atoms to the alkyl side chain of the conjugated polymer, and demonstrate high external quantum efficiency and high detectivity of OPDs.
