Abstract

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
Nb-doped TiO2 nanotube (with C-Nb < 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 TiO2 nanotubes. IMVS measurements indicate the beneficial effect to be due to lower recombination losses.
