  TiO2 nanorods have been prepared on ITO substrates by dc reactive magnetron
sputtering technique. The hydroxyl groups have been introduced on the nanorods
surface. The structure and the optical properties of these nanorods have been
studied. The dye-sensitized solar cells (DSSCs) have been assembled using these
TiO2 nanorods as photoelectrode. And the effect of the hydroxyl groups on the
properties of the photoelectric conversion of the DSSCs has been studied.
