采用水热法制备了部分纳米线结构的二氧化钛，然后在空气中焙烧。将合成的钛酸氢粉在300℃下焙烧4h，得到部分纳米线结构的二氧化钛。用部分纳米线结构的二氧化钛制备的薄膜厚度为5.6μm的染料敏化太阳能电池的性能优于完全纳米线结构的二氧化钛和传统的等轴纳米二氧化钛粉末。其短路电流密度为11.9 mA/cm~2，开路电压为0.754 V，填充因数为0.673，总效率为6.01%。讨论了一维纳米结构和电子高速路概念的影响。
Partially nanowire-structured TiO2 was prepared by a hydrothermal processing followed by calcination in air. The hydrogen titanate powder as-synthesized was calcined at 300 °C for 4 h to obtain the partially nanowire-structured TiO2. A dye-sensitized solar cell (DSC) with a film thickness of 5.6 μm, fabricated using the partially nanowire-structured TiO2 showed better performance than using a fully nanowire-structured TiO2 or a conventional equi-axed TiO2 nanopowder. The short-circuit current density (JSC), the open-circuit voltage (VOC), the fill factor (FF) and the overall efficiency (η) are 11.9 mA/cm2, 0.754 V, 0.673 and 6.01 %, respectively. The effects of one-dimensional nanostructure and electron expressway concept are discussed.
