Bamboo-Type TiO2 Nanotubes: Improved Conversion Efficiency in Dye-Sensitized Solar Cells

Bamboo-type TiO2 nanotube layers were produced by alternating voltage anodization of Ti. In comparison to smooth TiO2 morphologies the stratified nanotube structure shows significantly increased light harvesting and conversion efficiencies when used in dye sensitized solar cells.
