Abstract: The present invention relates to a dye-sensitized solar cell including patterned metal counter electrodes and a manufacturing method thereof. The dye-sensitized solar cell is manufactured by increasing the surface area simply by sputtering metal on a silicon wafer on which 30 nanometer patterns are formed. According to the present invention, as the surface area of a metal catalyst layer increases, electrodes for a dye-sensitized solar cell provide a sufficient surface area between the electrode and an electrolyte to activate ion exchange. As a result, the present invention can have high photoelectric conversion efficiency higher than an existing dye-sensitized solar cell. Furthermore, it is possible to easily form 30 nanometer fine metal patterns by sputtering metal on a silicon waver with patterns.
