Abstract

Size-tunable titanium oxide (TiO ₂) nanotube powders offering both a light-scattering effect and a light-harvesting function were synthesized by a fast and facile anodizing method. When used to prepare the TiO ₂ layer for a photoanode, their photovoltaic performances were much worse than that of a nanocrystal TiO ₂ layer. However, when the TiO ₂ nanotube powders were used as a light-scattering layer on a nanocrystal TiO ₂ layer, the highest conversion efficiency was obtained because of more noticeable light absorption of the longer wavelength, which was not attainable from a pure nanocrystal TiO ₂ layer or the combination of nanocrystal TiO ₂/commercialized light-scattering particles.
