D. S. Chung and co‐workers develop a smart strategy for a highly color‐selective polymer photodiode, on page 1933. By introducing a nonabsorbing acceptor, the absorption spectrum of the color‐selective donor can be fully reflected at the spectral response of the fabricated photodiodes. Furthermore, they adopt a planar heterojunction device architecture to optimize fast temporal response and low dark current. As a result, a high detectivity and narrow‐band blueselective photodiode is realized.
