摘　　要：通过恒压阳极氧化法在Ti箔表面制备了结构规整的TiO2纳米管阵列,研究了氧化时间和退火温度对纳米管阵列的尺寸和晶体结构的影响。用制得的纳米管阵列电极组装了染料敏化太阳能电池(DSSC),研究了纳米管长度、退火温度和电极面积对DSSC光电性能的影响。结果表明,纳米管管径和壁厚均与氧化时间无关,而纳米管长度则随着氧化时间延长而增加。在450℃及更低温度退火时,纳米管中只出现锐钛矿相;而在500℃退火时,纳米管中则又出现了金红石相。由厚度为27μm、退火温度为450℃的纳米管阵列电极组装成的DSCC具有最佳的光电转化性能。DSCC的光电转化效率随电极面积的增加而降低。Highly ordered TiO2 nanotube arrays were prepared by the anodic oxidation of pure titanium foil. The effects of oxidation time and annealing temperature on the size and crystal structure of the nanotube arrays were studied. And, dye-sensitized solar cells (DSSC) were assembled with the prepared TiO2 nanotube arrays electrodes. The effects of nanotube length, annealing temperature and electrode area on the photoelectric performance of the DSCC were investigated. The results show that the diameter and wall th...
