Triton Facilitated Spherical TiO sub(2) Nanoparticles and Their Advantage in a Dye-Sensitized Solar Cell

Spherical TiO sub(2) particles (60 nm) were obtained by using a Triton X-100. The surfactant was employed in two stages, i.e., in the hydrolysis of TiCl sub(4) and then in the precipitation of the corresponding Ti (IV) polymers. The advantages of such spherical TiO sub(2) particles were examined in...

Zusammenfassung:Spherical TiO sub(2) particles (60 nm) were obtained by using a Triton X-100. The surfactant was employed in two stages, i.e., in the hydrolysis of TiCl sub(4) and then in the precipitation of the corresponding Ti (IV) polymers. The advantages of such spherical TiO sub(2) 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 TiO sub(2) particles, compared with that of a cell using a TiO sub(2) film prepared without surfactant.
