Synthesis and formation mechanism of mesoporous TiO2 microspheres for scattering layer in dye-sensitized solar cells

This report describes a simple and low-cost method for preparing mesoporous TiO2 microspheres (TMs) for scattering layer in DSSCs. The maximum photoelectric conversion efficiency (η) of 9.33% has been achieved by the photoanodes made from TMs with a diameter of 400 nm, indicating a 24% increase in the η compared to the photoanode without scattering layer (7.45%).
