Highly ordered TiO 2 nanotubes grown on a Ti substrate are conveniently modified with samarium oxide (Sm 2 O 3 ) by a hydrothermal method for use in back-illuminated dye-sensitized solar cells. As a down-conversion luminescence material, samarium oxide improves the UV radiation harvesting and thus increases the photocurrent. The results show that Sm 2 O 3 -modified TiO 2 nanotubes can increase the short-circuit current and the conversion efficiency of dye-sensitized solar cells. When TiO 2 nanotubes are modified by 0.02 M Sm 2 O 3 , the efficiency is improved by 73.1% compared with bare TiO 2 nanotubes.
