We report on the fabrication of solid-state dye-sensitized solar cells with ZnO nanorods as n-type material and CuSCN as p-type material. The ZnO nanorods were grown on ITO-coated glass by using a low-temperature aqueous chemical growth approach employing different growth times. If the growth time is changed, the nanorod morphology can be varied in lentgh and diameter. CuSCN was deposited on the dye-coated ZnO nanorods from a solution in di-n-propyl sulphide, so that the nanorods are fully embedded in CuSCN. The ZnO/dye/CuSCN solar cells show photocurrents of 0.26 mA/㎠, an open circuit voltage of 0.34 V and an energy conversion efficiency of 0.1 %.
