Abstract—Highly ordered, self-organized TiO2 nanotube
arrays (TNA) have been successfully prepared by anodization
of titanium foil in ethylene glycol electrolyte containing 0.01%
ammonium fluoride (NH4F). The effect of variation of applied
anodization voltage ranging from 50V to 57 V on the
morphology of the TNA has been studied using field emission
scanning electron microscope. The increase in applied voltage
enhances average pore size from 34nm to 58nm and reduces
wall thickness. Diffuse reflectance spectroscopy has been used
to evaluate the amount of dye absorption on the surface of
various TNA which reveals direct correlation between the dye
absorption and the morphology of the sample.
Index Terms—Titanium dioxide, Dye-sensitized solar cell,
