摘　　要：将电沉积和溶剂热方法制备的ZnO纳米片阵列和ZnO纳米球组装成ZnO纳米片/纳米球复合结构光阳极,并应用透射电镜(TEM)、扫描电镜(SEM)、X射线衍射仪(XRD)对合成产物的形貌和晶相进行表征。染料敏化太阳电池性能测试表明,与单一光阳极结构的ZnO纳米片基电池相比,基于更大比表面积和更强光散射效应的ZnO纳米片/纳米球复合结构光阳极的电池具有更高的短路电流密度和开路电压,光电转换效率更高。ZnO nanoplate/nanosphere hybrid structures were successfully constructed by combining electrodeposited ZnO nanoplate arrays and solvothermally grown ZnO nanospheres, and used as the photoanode of dye-sensitized solar cells for the first time. The morphology and crystal phase of synthesized products were characterized by transmission electron microscopy （TEM） , scanning electron microscopy （SEM）and X-ray diffraction（XRD）. Performance tests of DSSCs（Dye-Sensitized Solar Cells）show that compared with ZnO nanoplate arrays-based DSSC, DSSC with a photoanode of ZnO nanoplate/nanosphere hybrid structures exhibits higher short-circuit current density, open-circuit voltage, and photoelectric conversion efficiency that profit from larger surface area and high light scattering effect in the photoanode of ZnO nanoplate/nanosphere hybrid structures.
