Multi-layered light scattering layer has been designed to improve the energy conversion efficiency of dye-sensitized solar cells (DSSCs) by scattering of the incident light. To enhance the light scattering properties, the surface of light scattering TiO2 particle was dual-coated with nano-sized Al2O3 and SiO2 particles by using a modified sol-gel method. Four kinds of the TiO2 electrodes with different thicknesses were fabricated and their photovoltaic effects on DSSCs were investigated. By increasing the thickness of light scattering layer, the total reflectance of working electrodes increased to 37%, resulting in an increase in the energy conversion efficiency up to 6.76%.
