A stacked organic photosensitive optoelectronic device optimized to enhance desired characteristics such as external quantum efficiency, current and voltage. The 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 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.
A mixed electrical configuration stacked organic photosensitive optoelectronic device comprising:
The device of 22 wherein the thicknesses of said plurality of photoconductive organic layers are selected to alter said molecular energy levels of excitons so as to form multiple quantum wells in said plurality of photoconductive organic layers.
