Self-aligned TiO2 nanotube arrays (20 mu m in length) were fabricated by anodic oxidation of Ti-grid with a thickness of 100 mu m in an ethylene glycol electrolyte with an addition of H2O (1.5 vol.%) and NH4F (0.2 wt.%). Voltage applied between Ti and Pt cathodes is 60 V at -22 degrees C. Dye-sensitized solar cell utilizing photoanode structure of TiO2-nanotube/Ti-grid was fabricated with no transparent conducting oxide (TCO) layer, in which Ti-grid replaces TCO. Overall photoconversion efficiency is very low (<05%) due to the large pore size (100 nm in diameter) of the nanotubes, which may cause insufficient dye molecules to be attached, thus limiting light harvesting.
