Abstract

Nb-doped TiO2nanotube (with CNb< 1 wt%) layers were successfully fabricated by self-ordered electrochemical anodization of Ti–Nb alloys. When used in dye-sensitized solar cells the efficiency enhanced by up to 30% compared to non-doped TiO2nanotubes. IMVS measurements indicate the beneficial effect to be due to lower recombination losses. [ABSTRACT FROM AUTHOR]
