摘　　要：文章通过Stober法合成粒径为300 nm的SiO_(2)纳米球,将该纳米球以乙醇为溶剂配置成一定浓度的悬浮液,通过旋涂法使其在染料敏化太阳能电池(dye-sensitized solar cells,DSSCs)的光阳极P25上形成一层薄膜,再将形成的P25-SiO_(2)复合膜放入TiO_(2)溶胶中浸泡一定时间,使得光阳极上的SiO_(2)纳米球被TiO_(2)纳米粒子包裹,形成SiO_(2)-TiO_(2)核壳结构薄膜。与没有散射层的DSSCs相比,以该核壳结构薄膜作为DSSCs的光散射层电池的光电转换效率提高了18%。In this paper,Stober method was applied to synthesizing 300 nm SiO_(2)nanospheres,which was dissolved in absolute ethyl alcohol to form a suspension liquid containing various concentrations.A nano-film was fabricated by coating SiO_(2)suspension liquid on P25 photoanode of dye-sensitized solar cells(DSSCs)via spin coating method.Then,the P25-SiO_(2)composite film was immersed in the TiO_(2) sol for a certain time.Therefore,the SiO_(2)nanospheres on P25 photoanode were packed by TiO_(2) nanoparticles and a film containing core-shell structure was obtained.When the SiO_(2)-TiO_(2) core-shell structure film was employed as the scattering layer of DSSCs,the efficiency of cells increases 18%compared with that of the DSSCs without the scattering layer.
