Preparation of ZnO nanorods conductive PET films and application in dye sensitized solar cells

以含氧化铟锡(ITO)镀层的PET薄膜为软基板制备染料敏化太阳能电池,并对电池的性能进行测试。在PET薄膜表面葡萄糖还原银氨溶液法在PET薄膜表面镀制银层,后在此银层上调控ZnO棒状结构的垂直生长。研究了醋酸锌浓度、生长时间对ZnO生长的影响,探究其在染料敏化太阳能电池中的应用。薄膜和ZnO棒的形貌用扫描电子显微镜(SEM)观察,ZnO结晶形态用X射线衍射(XRD)分析,组装的电池性能通过数字源表测定。结果显示,薄膜表面镀制的银层均匀且致密,生长的氧化锌纳米阵列规整;在镀银导电PET薄膜上生长的ZnO具有六方纤锌矿晶型;组装的染料敏化太阳能电池结构完整,具有有效的光电转换效率。

The dye-sensitized solar cells were prepared by PET films coated with indium tin oxide(ITO)as soft substrate,and the performance of the cells were tested.A silver layer was plated on the PET film surface by glucose reduction silver ammonia solution,on which the vertically arrayed ZnO rods were regulated.The effects of zinc acetate concentration and growth time on the growth of ZnO were studied,and its application in dye-sensitized solar cells was explored.The morphology of Ag layer and ZnO rods were observed by scanning electron microscopy(SEM),while the crystalline morphology of ZnO was analyzed by X ray diffraction(XRD),and the performance of the assembled cells were measured by digital source meter.The results showed that the silver layer on the film was uniform and compact,and the growth of ZnO nanorod was regular.The ZnO grown on silver-plated conductive PET film has a hexagonal wurtzite crystal.The assembled dye-sensitized solar cells have complete structure and effective photoelectric conversion efficiency.
