| 摘 要： | 采用溅射-置换(SD)法在导电玻璃(FTO)基底上制备了染料敏化太阳能电池(DSSC)对电极SD-Pt/FTO.形貌表征显示,和热解法(PY)所获得的对电极(PY-Pt/FTO)相比,SD法获得的对电极SD-Pt/FTO上Pt颗粒分散性显著改善.光电流-光电压特性曲线测试表明,以SD-Pt/FTO为DSSC对电极的光电转化效率比以PY-Pt/FTO为DSSC对电极的提高了16.5%.DSSC电池性能改善与SD-Pt/FTO对电极具有较低的电阻和由Pt颗粒分散性改善引起催化性能改善密切相关.

| Abstract: | APt/FTOelectrode for dye-sensitized solar cells (DSSC) was prepared by the sputtering (Cu) -displacement (Pt) (SD) method on a conductive glass (FTO) substrate (SD-Pt/FTO). Morphological characterization revealed that the dispersion of Pt particles on the SD-Pt/FTO electrode was significantly improved in comparison with the PY-Pt/FTO electrode prepared by the pyrolysis of Pt salts (PY). Optical current-voltage curves showed that the photoelectric conversion efficiency of DSSC with a SD-Pt/FTO counter electrode increased by 16.5% relative to that with a PY-Pt/ FTO counter electrode. The improvement of DSSC performance with the SD-Pt/FTO electrode is due to its lower electric resistance, and good catalysis resulting from the improved dispersion of Pt particles in the SD process compared with the PY process. |
