摘　　要：采用二氧化钛(P25)、粘接剂和溶剂经研磨制备致密二氧化钛薄膜,并结合水热法在致密薄膜上制备多孔二氧化钛薄膜,然后再将其浸渍在醋酸锌溶液中制备成TiO2/ZnO复合薄膜,将所制得的复合薄膜分别作为光阳极制备成染料敏化太阳能电池。通过对光电性能的比较研究,底层致密外层多孔二氧化钛薄膜远远优于致密二氧化钛薄膜,而在醋酸锌中浸泡80 min时所得TiO2/ZnO复合薄膜的光电性能最好,光电转换效率高达4.36%。Compact TiO2 film was prepared from TiO2 （）725）, adhesives and solvent by grinding and porous TiO2 film was prepared by hydrothermal method on the compact TiO2 film. Then TiOJZnO composite film could be obtained after the porous TiO2 film was dipped into zinc acetate solution. DSSC （dye-sensitized solar eel1） was assembled by the three kinds of films fabricated as photoanode respectively. Through the comparative study of the photoelectric properties, the film that the bottom is compact and the external is porous is better than the compact TiO2 film, and the TiO2/ZnO composite film dipped into zinc acetate solution for 80 minutes has the best photoelectric properties with high photoelectric conversion efficiency about 4.36%.
