Abstract(in English) Titanium oxide nanotubes are nanomaterials which draw attention as a negative electrode for a dye-sensitized solar cell (DSC). Anodization of titanium is a promising method to fabricate a vertically-oriented titanium oxide nanotube film on a transparent conductive oxide (TCO) layer. The application of an anodic titanium oxide nanotube film to a negative electrode of a DSC requires direct formation of a crystalline titanium oxide nanotube film of about 10 μm in thickness on a TCO layer. In this study, a titanium film deposited on a TCO layer by the DC magnetron sputtering method was anodized to form an anodic titanium oxide nanotube film, and it was annealed in oxygen atmosphere to crystallize. In addition, the crystalline nanotube film was applied to a DSC. The ideal factor n, the series resistance R_s and the shunt resistance R_ were estimated from the analysis of the I-V characteristic. In the result, the series resistance R_s was improved compared with a DSC using TiO_2 nanoparticles as a negative electrode.
