Polymer-nanocrystal photo device and method for making the same

Especially for reducing costs for photovoltaic cells, research is done all around the world for finding a solid state composition of creating an interpenetrating solid-state conducting material in a nanoporous network. Such device could also be used for LED (light emitting diodes), photo sensors, optical switches and even optical networks. This invention relates to a photo device comprising a layer of nanometer sized particles and a conducting polymer in solid state, wherein the nanometer sized particles are chosen from the group of TiO2, ZnO, CdSe, CdS, ZrO2, SnO2 and wherein the conducting polymer comprises PPV (polyparaphenylenevinylene) or a derivative thereof.
