ZnO nanoparticle-nanowire ͑NP-NW͒ array hybrid photoanodes for dye-sensitized solar cell ͑DSC͒ with NW arrays to serve as a direct pathway for fast electron transport and NPs dispersed between NWs to offer a high specific surface area for sufficient dye adsorption has been fabricated and investigated to improve the power conversion efficiency ͑PCE͒. The overall PCE of the ZnO hybrid photoanode DSC with the N3-sensitized has reached ϳ4.2%, much higher than both ϳ1.58% of ZnO NW DSC and ϳ1.31% of
