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 .
