Abstract In order to prepare the TiO2 liquid dispersions The low production costs, together with a good efficiency for the electrodes of dye-sensitized solar cells with indus- of energy conversion, reaching 10% in some cases, make trial mass production level at a reasonable cost, the present such devices a promising alternative for the development study investigates the preparation of TiO2 liquid disper- of a new generation of solar cells [1 4]. In order to achieve sions by a general industrial dispersion technique using high cell energy efficiency, much previous research has readily available P25.

using Cu K a radiation operated at 40 kV and 40 mA, and the first crystallite size of TiO 2 was calculated from a half- value width of the XRD peak at 2h = 25.4 using Scher-rer’s equation. The molar ratio of doped metal in TiO
