Fabrication and Evaluation of Titanium Dioxide Nanotube Thin Films by Anodic Oxidation on Transparent Electrodes

Abstract:

Titanium dioxide nanotube (TNT) thin films were fabricated, for application as the negative electrode of dye-sensitized solar cells (DSC), by anodic oxidation of titanium thin films deposited by RF magnetron sputtering on indium tin oxide glass substrates. Anodic oxidation was carried out by a constant voltage or constant current method in an electrolyte in order to determine the best method to increase TNT film thickness. Thick titanium dioxide films were fabricated by the constant voltage method at higher voltages. Thicker titanium dioxide films were obtained by the constant current method compared to the constant voltage method. However, the constant current method with optimal current yielded TNT films with higher quality (high transparency). The power conversion efficiency of DSC was improved using films fabricated by the constant current method.
