摘要
采用电泳沉积法,在FTO/介孔TiO2薄膜上制备了介孔TiO2/单壁碳纳米管(SWCNTs)薄膜电极,用Raman和SEM等手段对薄膜电极进行了表征.结果表明,SWCNTs已沉积到介孔TiO2薄膜上.分别用四羧基苯基卟啉(TCPP)和联吡啶钌化合物N719对其进行敏化,并组装成太阳能电池.研究结果表明,与单纯的TiO2粒子膜相比,介孔TiO2和SWCNTs的紧密结合可使得光生电子更容易传输,光电转换效率显著提高.
Mesoporous TiO2/SWCNTs thin films were successfully prepared through electrophoretic deposition method on FTO/meso-TiO2 substrate. The products were characterized by Raman and SEM. The results reveal that SWCNTs are successfully deposited on the surface of mesoporous TiO2 thin film. The dye-sensitized solar cells are assembled with the films and they are sensitized by TCPP and N719, respectively. The results show that they exhibite enhanced power conversion efficiency. This maybe attribute to the compact contact of mesoprous TiO2 and SWCNTs in favor of the transportation of photogencrating electrons.
