Abstract

Highly ordered TiO ₂ nanotubes grown on a Ti substrate are conveniently modified with samarium oxide (Sm ₂O 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 ₂O 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 ₂O ₃, the efficiency is improved by 73.1% compared with bare TiO ₂ nanotubes.
