Here, we report forsythia-like TiO₂-decorated SnO₂ nanowires on fluorine-doped SnO₂ electrode as a photoelectrode of dye-sensitized solar cells. When SnO₂ nanowires grown via vapor-liquid-solid reaction were soaked in TiCl₄ solution, leaf-shaped rutile TiO₂ was grown onto the surface of the nanowires. The TiO₂ decoration increases the short circuit current (J_sc), open circuit voltage (V_oc) and fill factor (FF) of dye-sensitized solar cells. Further, electron lifetime increased by employing an atomic-layer-deposited TiO₂ nanoshell between the TiO₂ leaves and the SnO₂ nanowire, due to preventing charge recombination at the nanowire/electrolyte interface.
