The effect of light scattering layers (400 nm, TiO particle) of 4 m thickness on the dye-sensitized solar cell has been investigated with a 12 m thickness of photo-anode (20 nm, TiO particle). Two different structures of scattering layers (separated and back) were applied to investigate the light transmitting behaviors and solar cell properties. The light transmittance and cell efficiency significantly improved with inserting scattering layers. The back scattering layer structure had more effective transmitting behavior, but separated scattering layer (center: 2 m, back: 2 m) structure (9.83% of efficiency) showing higher efficiency (0.6%), short circuit current density (0.26 mA/cm) and fill factor (0.02). The inserting separating two scattering layers improved the light harvesting, and relatively thin back scattering layer (2 m of thickness) minimized interruption of ion diffusion in liquid electrolyte.
