中文摘要：

摘要：采用醇热法，以醋酸锌（zn（AC）2·2H2O）、一缩二乙二醇（C7H40O5）和二水乙酸锂（Li（Ac）2·2H2O）为原料制备了具有多级结构的Zn0微球。主要研究了ZnO浆料制备工艺和膜厚对电池性能的影响。采用xRD对Zn0粉进行物相分析、采用SEM对ZnO粉的形貌进行了表征，采用电化学工作站对电池的电化学性能进行了分析，并测试了电池的I—V曲线。结果表明：球磨时间5h，膜厚为20μm条件下得到的电池性能最好，该电池的光电转换效率达到3．59％，开路电压Voc为0．60V，短路电流密度Jsc为8．66mA／cm2，填充因子FF为0．64。

英文摘要：

Hierarchically structured ZnO microspheres were prepared through alcohol thermal method by using zinc acetate, diethylene glycol and lithium acetate as raw materials. The effects of slurry preparation process and thickness of photoanode on the properties of the DSSCs were mainly studied. XRD and SEM were used to characterize the phase composition and morphology of the synthesized samples. Photocurrent-voltage curves （I-V curve） and electrochemical impedance spectroscopy （EIS） were given. ZnO hierarchy structure would be destroyed by milling while remain intact by vortex method. The DSSC assembled by photoanode with milling slurry for 3 h and 20 μm thickness of membrane achieved an optimum efficiency of 3.39%. In addition, the Voc, Jsc and FF was 0.60 V, 8.66 mA/cm2 and 0.64 respectively.
