Abstract

Light harvesting in a TiO2 nanotube-based dyesensitized solar cell can be greatly enhanced by coupling to a TiO2 nanotubular photonic crystal with periodic structure along the axial direction, as demonstrated by Haitao Huang, Limin Zhou, and co-workers. The TiO2 nanotubes and nanotubular photonic crystal are synthesized by a single anodization process, ensuring good physical contact and easy electrolyte infiltration.
