使用经少量氯铂酸处理过的金属钛板作为基底,采用化学气相沉积法获得多壁碳纳米管。扫描电镜观察表明,经过氯铂酸处理过的钛板比未经过处理的钛板表面粗糙度低,获得的碳纳米管有一定取向性。将这种复合体系用作染料敏化太阳能电池的对电极,制作电池并测量其光电性能。与使用未经处理的多壁碳纳米管/钛板对电极的电池相比,使用经过氯铂酸处理的取向多壁碳纳米管/钛板复合体系的电池的开路电压Voc、短路电流密度Jsc及填充因子ff均有明显提高,分别达到了741 mV,8.99 mA/cm2和0.49。
Multiwalled carbon nanotubes were obtained by chemical vapor deposition using a small amount of chloroplatinic acid-treated titanium plate as a substrate. Scanning electron microscopy showed that after chloroplatinic acid treatment of titanium than untreated titanium surface roughness is low, the obtained carbon nanotubes have a certain orientation. This composite system was used as the counter electrode of a dye-sensitized solar cell, a cell was fabricated, and its photoelectric properties were measured. The cell open circuit voltage Voc using a chloroplatinic acid-treated oriented multi-walled carbon nanotube / titanium composite system, as compared to a cell using an untreated multi-walled carbon nanotube / titanium counterelectrode, exhibited a short circuit current density Jsc And fill factor ff were significantly improved, respectively, reached 741 mV, 8.99 mA / cm2 and 0.49.
