Thin nanoporous TiO
2
film with a metal-based light reflective layer was investigated in dye sensitized solar cell (DSSC). In cost-effective DSSC module, the thickness reduction of the nanoporous TiO
2
film was used to reduce the photoactive dye loading. However, the thin nanoporous TiO
2
film has poor light scattering ability so that the film is generally optical transparency, which means many transmitted light would be lost in the electrolyte solution. In order to improve the light scattering issue, we proposed a metal-based light reflective layer which was used on the thin nanoporous TiO
2
film to reflect the transmitted light readdressing in the film. The results show that the photovoltaic performance of DSSC was enhanced when using the metal-based light reflective layer.
