NOVELTY - Transparent electrode (110) comprises a photocatalytic layer (105) formed on a transparent electrode and having a photocatalytic compound. A metal mesh layer (107) is formed on the photocatalytic layer. An electrically conductive layer (109) is formed of an electrically conductive material coated on the metal mesh layer.    USE - The transparent electrode is used in producing semiconductor electrode for solar cells, e.g. dye-sensitized solar cell.    ADVANTAGE - The solar cell that utilizes the transparent electrode has high-efficiency characteristics. It has high transmittance and low electrical resistance characteristics while providing a good UV-blocking performance that reduces the deterioration of the dye and the electrolyte. The transparent electrode improves the solar cell and extends the life cycle of the solar cell. It can be manufacture inexpensively via a simple process.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) method for manufacturing the above transparent electrode for solar cells comprising coating the photocatalytic compound on a transparent substrate (103) to form the photocatalytic layer, coating a water-soluble polymer layer on the photocatalytic layer to form a water-soluble polymer layer, exposing the photocatalytic layer and the water-soluble polymer layer to light through a photomask, plating the exposed substrate with a metal to form the metal mesh layer, and coating the electrically conductive layer on the metal mesh layer;    (2) semiconductor electrode (100) for solar cells comprising a transparent electrode, a metal oxide (123) layer and a dye (125) adsorbed on the surface of the metal oxide layer; and    (3) dye-sensitized solar cell comprising a semiconductor electrode.
