ORGANIC PHOTOVOLTAIC CELLS UTILIZING ULTRATHIN SENSITIZING LAYER

摘要

A method of fabricating a photosensitive optoelectronic device, comprising: depositing a first organic photoconductive material over a first electrode to form a first continuous layer; depositing a second organic photoconductive material over the first continuous layer to form a first discontinuous layer comprising a plurality of islands; depositing a third organic photoconductive material over the first discontinuous layer to form a second continuous layer; and depositing a second electrode over the second continuous layer, wherein one of the first organic photoconductive material and the second organic photoconductive material consists essentially of a donor host material, and another of the first organic photoconductive material and the second organic photoconductive material consists essentially of an acceptor host material, and the second organic photoconductive material is a sensitizer having an absorption spectra different from the donor host material and the acceptor host material.
