摘要:
为了进一步提高染料敏化太阳能电池的光电转换效率，采用水热法制备质子钛酸盐纳米棒，并在300,500〖KG3x〗℃和700〖KG3x〗℃下分别对上述样品烧结得到二氧化钛纳米棒。利用扫描电子显微镜和X射线衍射分析手段对样品进行了表征。将上述样品组装成染料敏化太阳能电池，并对其进行光电性能测试。测试结果表明700〖KG3x〗℃烧结得到的二氧化钛纳米棒具有最高的光电转换效率为113%。交流阻抗，强度调制光电流谱和光电压谱测试结果进一步显示700〖KG3x〗℃烧结得到的锐钛矿纳米棒具有较低的电荷转移电阻，快速的电子转移速率和较长的电子寿命。上述结果表明高温烧结得到的二氧化钛纳米棒电子-空穴复合几率少，电子收集效率高，相应的光电转换效率也高。
Abstract:
Hydrothermally synthesized titanate nanorods are calcined at three different temperatures (300, 500, 700〖KG3x〗℃). The prepared samples are characterized by scanning electron microscope / transmission electron microscopy and X-ray diffraction. These samples are used to fabricate photoelectrodes for dye-sensitized solar cells. It is found from current voltage curve measurements that dye-sensitized solar cells with anatase nanorods calcined at 700〖KG3x〗℃ shows the best photoelectrochemical performance, with a photovoltaic conversion efficiency of 113%. Electrochemical impendence spectroscopy (EIS), intensity-modulated photocurrent spectroscopy (IMPS), and intensity-modulated voltage spectroscopy (IMVS) are used to further investigate the kinetics process of TiO2 lm electrodes. The results indicate that the anatase nanorods, calcined at 700〖KG3x〗℃, have a lower charge-transfer resistance, a faster transport time and a longer electron lifetime, implying lower electron-hole recombination and a higher charge-collection efciency.
