Abstract

Disclosed herein are organic photosensitive optoelectronic devices comprising at least one hybrid planar-graded heterojunction. In particular, organic photosensitive optoelectronic devices are disclosed having two electrodes (110), (150) in superposed relation, a graded heterojunction layer (130) located between the two electrodes, and at least one photoactive layer (120), (140) adjacent to and interfacing with the graded heterojunction layer.
