Dye-Sensitized Solar Cell Fabrication with Hydrothermal Synthesized TiO2 and Evaluation the Power Generation Efficiency

TiO2 powder was synthesized hydrothermally from titanium alkoxide ethanol solution in supercritical state and obtained anatase type crystalline powder sized ca. 20 nm. Dye-sensitized solar cells were fabricated with the powders and evaluated the power generation efficiencies.
