Abstract
The sub-micron size anatase TiO2 particles with size about 0.2-0.3 μm were synthesized with basic peptizing agent and hydrothermal method and added into TiO2 film as light scattering center. The addition of the sub-micron size anatase TiO2 particles enhanced light scattering and dye adsorption abilities of the TiO2 film. When the weight proportion of the sub-micron size/nano-size TiO2 particles in the TiO2 film attained to 1.25/10, the highest energy conversion efficiency about 7.41% was obtained, which was 23% enhancement comparing with the TiO2 film containing pure nano-size TiO2 particles. It presented an efficient way for improving the photovoltaic performance of dye-sensitized solar cell.
