Rapid Charge Transport in Dye-Sensitized Solar Cells Made from Vertically Aligned Single-Crystal Rutile TiO2 Nanowires

A rapid solvothermal approach was used to synthesize aligned 1D single‐crystal rutile TiO2 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...

Summary:A rapid solvothermal approach was used to synthesize aligned 1D single‐crystal rutile TiO2 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.
