A solid-state dye-sensitized solar cell (DSC) is fabricated by using arrays of 11-12 µm 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.
采用阵列形式的 11-12 µm 长、垂直取向的 ZnO 纳米线作为阳极，并用 CuSCN 作为固态空穴传输材料，制备了固态染料敏化太阳能电池（DSC）。与之前报道的基于一维纳米结构（JSC = 0.34 mA cm-2）或 ZnO 纳米多孔纳米晶结构（JSC = 4.5 mA cm-2）的固态 DSC 的报道数据相比，所制备的 DSC 具有显著更高的光电流密度（JSC = 8 mA cm-2）。在 AM 1.5 G 模拟太阳光的照射下，报告的功率转换效率为 1.7%。
