摘　　要：采用水热法在TiO_2薄膜上制备ZnO纳米花,通过研究氢氧化钠溶度对ZnO纳米花生长形貌的影响,并调整工艺以优化ZnO纳米花形貌;同时把TiO_2/ZnO复合薄膜光阳极组装成染料敏化太阳能电池,通过测试得出J-V、EIS曲线。结果表明,基于TiO_2/ZnO复合薄膜染料敏化太阳能电池开路电压0.80 V,短路电流4.65mA/cm^2,转化效率2.32%;其性能优于单一的TiO_2染料敏化太阳能电池。In this paper,Introduces the synthesis of flower-like ZnO by hydrothermal method.Research on the concentration of sodium hydroxide’s impact on the structure of flower-like ZnO indicates that synthesis of flow-er-like ZnO depends on the concentration of sodium hydroxide.The dye-sensitized solar cell （DSSC）was assem-bled using TiO2/ZnO composite filmed photoanodes and current-voltage （J-V）characteristics under illumina-tion of AM1.5 simulated sunlight with a power density of 100 mW/cm2 .I-V and EIS curves were analyzed.The results show that,The open circuit voltage （UOC）of TiO2/ZnO composite film photoanode of DSSC is 0.80 V;ISC is 4.65 mA/cm2;ηis 2.32%.The performance of TiO2/ZnO composite film photoanode of DSSC are better than that of the pure TiO2 .
