摘要：

ZnO/TiO2 nanotubes were prepared using ZnO nanorods as raw materials, which were synthesized by hydrothermal methods. Then its performance as an electrode of a dye-sensitized solar cell was Investigated. The obtained products were characterized by SEM, XRD, EDX and N-2 adsorption. Furthermore, the photoelectric properties of ZnO/TiO2 nanotubes film electrodes calcined at different temperatures were investigated by UV-Vis adsorption spectra and electrochemical workstation. It is found that the DSSC based on ZnO/TiO2 nanotubes calcined at 600 C have optimum photoelectric properties, J=2.28 mA/cm(2) and V-oc= 0.631 V, yielding the 0.66% maximum conversion efficiency. Additionally, after TiCl4 posttreatment, the performance of DSSC made from ZnO/TiO2 nanotubes are improved obviously and the photoelectric conversion efficiency is up to 1.06%.
