摘要：
We report the comparative study of TiO2 nanoflower (NF) and TiO2-ZnO composite NF in terms of properties and dye-sensitized solar cell performances. TiO2 NF has been constructed by using the simple liquid phase deposition (LPD) method while TiO2-ZnO composite NF was prepared by using dip-coating method in which the as-prepared TiO2 NF was immersed into ZnO growth solution. The power conversion efficiency of the DSSC utilizingTiO(2)-ZnO composite NF is higher (0.62 +/- 0.02%) compared to TiO2 NF (0.17 +/- 0.10%) due to higher photon absorption, dye loading, R (cr,) and longer electron life time than those of TiO2 NF.
