Abstract
An organic photodetector including an electron blocking layer, where the electron blocking layer prevents and/or reduces dark current by preventing electrons traveling from the organic photodetector's anode to the organic photodetector's photoactive layer during dark, photon-less conditions. The electron blocking layer is formed from a compound having the formula: [M]a+[X]a— (General Formula (I)) where: M is a metal; X is CN, SCN, Se CN or TeCN; and a is at least 1.
