摘要：

A solid-state dye-sensitized solar cell (DSC) is fabricated by using arrays of 11-12 mu m long, vertically oriented ZnO nanowires as the anode and CuSCN as the solid hole-transport material. The fabricated DSC yields a remarkably higher photocurrent density (J(SC) = 8 mA cm(-2)) compared to previously reported data for solid-state DSCs based on either one-dimensional nanostructures. J(SC) = 0.34 mA cm(-2)) or nanoporous nanocrystalline structures. J(SC) = 4.5 mA cm(-2)) of ZnO. A power conversion efficiency of 1.7% under an irradiation of AM 1.5 G simulated sunlight is reported.
