| US2006102226 A UPAB: 20060616 NOVELTY - Producing a photoelectrode (3) of a solar cell involves applying a layer (2) of a nanocrystalline semiconductor material on a substrate (1) and then sintering at a sintering temperature, and introducing elongated particles into the layer which burn out at the sintering temperature and leave elongated cavities in the layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for solar cell having a photoelectrode produced by the inventive method, comprising: (A) nanoporous layer of semiconductor material; (B) counter electrode (6); and (C) electrolyte (5) or a polymer hole conductor, which passes through the nanoporous layer, between the photoelectrode and the counter electrode, where the layer of the semiconductor material has elongated cavities. USE - The method is used for producing a photoelectrode of a dye sensitized solar cell (claimed). ADVANTAGE - The method permits producing photoelectrodes for dye solar cells which allow sufficient diffusion of the electrolyte into the photo-electrode and thus a sufficiently great photocurrent even in the case of high viscous electrolytes. | |||||||||
