采用超声水热联合的方法,用商品P25为原料制备出直径10nm,长600nm的TiO2纳米管,通过X射线衍射(XRD)、扫描电子显微镜(SEM)、电子衍射(SAED)和透射电子显微镜(TEM)对产物进行表征.用TiO2纳米管制作薄膜电极并研究其光散射性能,结果表明TiO2纳米管可以作为染料敏化太阳能电池中薄膜工作电极内的光散射中心,增大光能的吸收.掺有10%小颗粒的纳米管薄膜电极具有强的光散射性能和良好的机械性能,可用做高效率染料敏化太阳能电池的工作电极.
TiO2nanotubes with diameter of 10nm and length of 600nm were prepared by commercial hydrothermal method with P25 as raw material. The structure of the nanotubes was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), electron diffraction (SAED) and transmission electron microscopy TEM) was used to characterize the product.The fabrication of thin film electrodes with TiO2 nanotubes and their light scattering properties were investigated. The results showed that TiO2 nanotubes could be used as the light scattering center in the working electrode of dye-sensitized solar cells and increase the absorption of light energy. The nanotube thin-film electrode doped with 10% of small particles has strong light-scattering properties and good mechanical properties, and can be used as a working electrode for high-efficiency dye-sensitized solar cells.
