Nanocrystalline TiO2 is one of the important compositions in dye sensitized solar cell. To control the size and phase of the nanocrystalline TiO2 in the process of the sol gel, the heat treat method and the results of the experiment have been greatly introduced. The D hkl(a) of anatase nanocrystalline TiO2 increases with the temperature raising and there is 43% rutile nanocrystalline TiO2 in the powders when temperature reach 270℃ and hydrolyze pH～1. The results show that the D hkl(r) of rutile nanocrystalline TiO2 is larger than the D hkl(a) of anatase nanocrystalline TiO2. Applying the nanocrystalline TiO2 in solar cell, the result that measured by the automatic measuring and data acquisition system prove good efficiency with right temperature.
Key words： nanocrystalline TiO2; sol gel; solar cell; efficiency
