摘要
将水热法制备的TiO2纳米管在600℃下焙烧,用焙烧产物制备染料敏化太阳能电池中的薄膜电极,同时与未焙烧的TiO2纳米管制备的薄膜电极进行光电性能比较。结果表明,600℃焙烧纳米管产物制备的薄膜电极短路电流和开路电压分别达到17.45mA/cm2和0.60V,光电转化效率提高到5.65%,高于未焙烧的TiO2纳米管制备的薄膜电极相应值,且机械性能良好,不易剥落。
TiO2 nanotubes were prepared via a hydrothermal reaction, and then sintered at 600 ℃. The resulting product was used to make the working electrode in dye-sensitized solar cells. The photoelectric properties of TiO2 nanotubes with and without sintering were compared. It was found that TiO2 films composed of TiO2 nanotubes sintered at 600 ℃ exhibited a light-to-electricity conversion efficiency of 5.65% with a short-circuit current of 17.45 mA/cm^2 and an open-circuit voltage of 0.60 V ; these values are much higher than those obtained using the non-sinmechanical properties and did not flake off easily.
