A light scattering TiO2 layer was investigated in dye-sensitized solar cells. To enhance the efficiency by light scattering layer in DSSCs, surfaces of the light scattering TiO2 particles were modified by thin oxide layer such as Al2O3. The surface of the TiO2 powder was coated with Al2O3 nanoparticles using simple methods, which was a kind of the modified sol-gel method. The Al2O3-coated TiO2 powder was characterized by SEM and XRF. The overall conversion efficiency of the DSSCs with the Al2O3-coated TiO2 light scattering layer increased from 5.07% to 6.46% compared to the DSSCs with the non-coated one.
