ZnO nanowire networks featuring excellent charge transport and light scattering properties are grown in situ within TiO2 films. The resultant TiO2/ZnO composites, used as photoanodes, remarkably enhance the overall conversion efficiency of dye-sensitized solar cells (DSSCs) by 26.9%, compared to that of benchmark TiO2 films.
