文章采用阳极氧化法在金属T i片基底上制备出T iO2纳米管阵列,并在450℃下退火1 h随炉冷却;对制备的TiO2纳米管采用连续离子沉积法沉积CdS量子点,得到不同CdS量子点吸附量的 TiO2纳米管。结果表明:T iO2纳米管为很高结晶度的锐钛矿结构,纳米管长度约为3μm ,管外径为110 nm ,内径为60 nm ;随着CdS量子点吸附量的增加,其对380~530 nm波段的光吸收效率也增加,从而提高了太阳能电池性能。

TiO2 nanotube arrays were prepared by anodic oxidation method in the base of the metal Ti film and annealed at 450 ℃ for 1 h with furnace cooling .CdS quantum dots were deposited on TiO2 nanotubes by continuous ion deposition method to get TiO2 nanotubes with different CdS quantum dots adsorption amount .It is found out that TiO2 nanotubes show anatase structure with a high de-gree of crystallinity ,the length of the nanotubes is about 3μm ,the tube external diameter is 110 nm , and the inner diameter is 60 nm .With the increase of the adsorption amount of CdS quantum dots ,the absorption intensity of 380-530 nm wavelength band increases ,the light absorption efficiency of TiO2 nanotubes is significantly raised ,so the solar cell performance is improved .
