Hierarchically structured nanotubes for highly efficient dye-sensitized solar cells

Adv Mater. 2013 Jun 11;25(22):3039-44. doi: 10.1002/adma.201205274. Epub 2013 Mar 1.


Hierarchical TiO2 nanotube arrays grown on Ti foil are yielded by subjecting electrochemically anodized, vertically oriented TiO2 nanotube arrays to hydrothermal processing. The resulting DSSCs exhibit a significantly enhanced power conversion efficiency of 7.24%, which is a direct consequence of the synergy of higher dye loading, superior light-scattering ability, and fast electron transport.
