摘　　要：本文采用一步电化学沉积的方法在导电玻璃上先后沉积了ZnO/染料复合薄膜以及CuSCN薄层,实现仅以电沉积法制备结构为ZnO/染料/CuSCN的固态染料敏化太阳能电池,电池的光电转换效率达到0.1%。在电沉积CuSCN前,脱附电沉积制备的ZnO/染料复合薄膜中的染料以形成多孔ZnO薄膜,然后通过染料再吸附得到染料敏化ZnO纳晶多孔薄膜。在电沉积过程中,ZnO和CuSCN的晶体尺寸、晶体取向和膜层形貌都可以进行比较精准的控制。探讨了影响沉积薄膜形貌和光电转换效率的因素,如旋转圆盘电极的旋转速度、电沉积温度以及染料敏化剂的选择。本文报道的低温电沉积制备全固态太阳能电池的方法为制备柔性染料敏化太阳能电池提供了一种新的思路。Onestep electrochemical deposition method was employed to serially deposit a ZnO/dye hybrid thin film on the conducting glass substrate and then a CuSCN thin layer. Thus a solid-state dye-sensitized solar cell with structure of ZnO/dye/CuSCN was fabricated only by the electrodeposition method, and the photoelectric conversion efficiency of the fabricated solar cell attained 0. 1 ~. Prior to deposition of CuSCN, the dye was first extracted from the as-prepared ZnO/ dye hybrid thin film to form porous ZnO thin film, and then dye-sensitized ZnO nanoporous thin film was prepared by readso CuSCN can be accurate rp ly tion of dye. Crystal size, growth orientation and morphology of ZnO and controlled by the electrochemical deposition approach, respectively. The factors such as rotating speed of the rotating disk electrode, temperature of electrodeposition, addition of different dyes, to influence the morphology of the as-deposited thin films and the photoelectric conversion efficiency of the as-prepared solar cells were also studied in this paper. The electrochemical deposition operated at low temperature opens a way to fabricate flexible dye-sensitized solar cells in future.
