摘要

Nanocrystalline TiO_2 thin film electrodes have been prepared from mixed pastes of tetrabutyl titanate and nanocrystalline TiO_2 particles by common pressure hydro-thermal method at low temperature. The tetrabutyl titanate was hydrolyzed and crystallized into, anatase TiO_2 to interconnect nanocrystalline TiO_2 particles and adhere them to conductive substrates, obtaining highly porous and mechanically stable TiO_2 nanocrystalline film. The conversion efficiencies of the dye-sensitized solar cells based on prepared electrodes on conductive glass substrates and flexible substrates were 4.8 percent and 1.9 percent under illumination of 100 mW/cm~2, respectively.
