ABSTRACT

Spherical TiO₂ particles (60 nm) were obtained by using a Triton X-100. The surfactant was employed in two stages, i.e., in the hydrolysis of TiCl₄ and then in the precipitation of the corresponding Ti (IV) polymers. The advantages of such spherical TiO₂ particles were examined in terms of photovoltaic characteristics of a dye-sensitized solar cell (DSSC) using Orange IV dye as sensitizer. Significantly higher overall solar energy conversion efficiency was obtained for a DSSC using the film of these spherical TiO₂ particles, compared with that of a cell using a TiO₂ film prepared without surfactant.
