<P>PROBLEM TO BE SOLVED: To provide a dye-sensitized solar cell of which photoelectric conversion efficiency is improved, with manufacturing thereof being of low cost, and a semiconductor electrode or a titanium oxide film that can be applicable to the dye-sensitized solar cell. <P>SOLUTION: In a carbon nano-tube structure, titanium oxide is carried or covered on a carbon nano-tube whose G/D ratio is 2-20 and length is 100 μm or longer. In a semiconductor electrode, a semiconductor layer is stacked which has a carbon nano-tube structure according to claim 1 on at least one conductive layer surface formed on a substrate in which a conductive layer is formed at least on one surface, with the titanium oxide on the electrode surface adsorbing dye. The dye-sensitized solar cell is characterized in that the semiconductor electrode is used for a photoelectrode. <P>COPYRIGHT: (C)2013,JPO&INPIT |
