  • Patent number: 8143516
    Abstract: A high capacity dye-sensitized solar cell module where a plurality of unit cells are simultaneously formed at a substrate in a simplified manner with increased light absorption efficiency. The dye-sensitized solar cell module includes first and second conductive substrates facing one another with regions for a plurality of unit cells. First and second electrodes are formed on the first or the second substrate such that the first and the second electrodes face one another at the respective unit cells. A dye is adsorbed at the first electrode. The space between the first and the second substrates at the respective unit cells is filled with an electrolyte. Insulation regions are formed on at least one of the first and the second substrates between a pair of unit cells neighboring to one another. The pattern of insulation regions, on one or both of the substrates, results in the unit cells being coupled in series, in parallel, or in a combination manner.
