摘要：

Highly ordered TiO2 nanotubes grown on a Ti substrate are conveniently modified with samarium oxide (Sm2O3) 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 Sm2O3-modified TiO2 nanotubes can increase the short-circuit current and the conversion efficiency of dye-sensitized solar cells. When TiO2 nanotubes are modified by 0.02 M Sm2O3, the efficiency is improved by 73.1% compared with bare TiO2 nanotubes. (C) 2012 Elsevier B.V. All rights reserved.
