Abstract

A rapid solvothermal approach was used to synthesize aligned 1D single-crystal rutile TiO 2 nanowire (NW) arrays on transparent conducting substrates as electrodes for dye-sensitized solar cells. The NW arrays showed a more than 200 times faster charge transport (see picture) and a factor four lower defect state density than conventional rutile nanoparticle films.
