The Influence of the Nanoparticles TiO_2 Films in Solar Cells

Wang Ruibin Dai Songyuan Wang Kongjia (Institute of Plasma Physics, Chinese Academy of Sciences, Hefei 230031 )  
Nanocrystalline TiO 2 is one of the important compositions in dye sensitized solar cell. To control the size and phase of the nanocrystalline TiO 2 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 TiO 2 increases with the temperature raising and there is 43% rutile nanocrystalline TiO 2 in the powders when temperature reach 270℃ and hydrolyze pH~1. The results show that the D hkl(r) of rutile nanocrystalline TiO 2 is larger than the D hkl(a) of anatase nanocrystalline TiO 2. Applying the nanocrystalline TiO 2 in solar cell , the result that measured by the automatic measuring and data acquisition system prove good efficiency with right temperature.
