Highly efficient organic UV photodetectors that are not sensitive to visible radiation (“visible‐blind”) but to UV‐A radiation are fabricated using an organic donor–acceptor couple. High external quantum efficiencies (EQEs) comparable to commercial GaN devices, but covering the entire UV‐A range (see Figure), make these devices promising for environmental and biomedical UV‐sensing applications.
