Patent ID: 8269100

Claim:
A hybrid photovoltaic cell device for generating electrical energy, comprising: a composite substrate for receiving solar radiation comprising: a first surface; a second surface disposed substantially opposite the first surface, an electron-accepting material characterized by a plurality of nanoscopic holes; and an organic electron-donating material disposed within at least some of the plurality of nanoscopic holes; an electrically conductive substrate proximate the first surface, the electrically conductive substrate in electrical communication with the composite substrate; and an electrode proximate the second surface, the electrode in electrical communication with the composite substrate, wherein the organic electron-donating material comprises a conjugated polymer wherein the organic electron-donating material comprises a plurality of two or more layers of conjugated polymer with each of the conjugated polymer layers having a different polymer length and a first layer of the conjugate polymer having a longest polymer length and a smallest optical bandgap and the other of the two or more layers having incrementally larger optical bandgaps and associated shorter polymer length.
