Organic photosensitive optoelectronic device

摘要

A stacked organic photosensitive optoelectronic device optimized to enhance desired characteristics such as external quantum efficiency, current and voltage. The 5 photosensitive optoelectronic device has a plurality of photosensitive optoelectronic subcells electrically configured in subassemblies of two or more subcells electrically configured in series or in parallel. The subassemblies may be electrically configured in series or parallel. The substrate may be the bottom electrode or there may be a bottom electrode distinct from the substrate. Each subcell comprises one or more organic 10 photoconductive layers between electrode layers or charge transfer layers. In one embodiment the top electrode is transparent. In other embodiments two or more electrodes are tarnsparent. In other embodiments photosensitive optoelectronic devices with multilayer photoconductive structures and photosensitive optoelectronic devices with a reflective layer or a reflective substrate are disclosed.
