摘要：

The nano-and microstructures of titanium dioxide (TiO2) photoanodes in photovoltaic cells have a large impact on their photon to electron performances, including light harvesting, photogenerated electron separation, transport and recombination. This review will focus on anodic TiO2 nanotubes (NTs) for the enhancement of photon conversion or light harvesting when incorporated in sensitized solar cells, which is valuable for increased photocurrent densities and solar cell efficiencies. By modulating the electrochemical processes which have a great impact on TiO2 NT geometry, excellent optical properties can be achieved, resulting in the enhanced absorption of incident light and reduced light loss via reflection, penetration or transformation. The results indicate that the control of structures and morphologies of TiO2 NTs is critical to the optimization of their applications in sensitized solar cells.
