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.
