Findings

Hydroxyl groups alter the surface properties of TiO2 nanorods.

Surface hydroxylation affects the optical properties of the nanorods.

The presence of hydroxyl groups influences the overall efficiency of DSSCs.

Abstract

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.
