采用电沉积-置换法在Ti片上制备了染料敏化太阳能电池( DSSC)的对电极Pt/Ti.形貌表征结果显示，与传统热解法制备的Pt/FTO对电极相比， Pt/Ti对电极Ti基底上Pt催化颗粒的粒径和分散性得到显著改善.光电流-光电压特性曲线测试结果表明，以Pt/Ti为对电极的DSSC与以Pt/FTO为对电极的DSSC相比，光电转化效率提高了20.8%.由于Pt颗粒分散性和粒径的改善所引起的Pt催化性能的提高、Pt/Ti对电极更低的电阻以及Ti基底更好的反光性能是提升DSSC性能的原因.

A Pt/Ti counter electrode of dye-sensitized solar cell( DSSC) was prepared by displacing electro-deposited Cu on a Ti sheet in H2 PtCl6 solution. Morphological characterization of the Pt/Ti electrode shows that the dispersion and size of Pt particles on Ti substrate is significantly improved in contrast to that of the Pt/FTO electrode prepared by pyrolysing Pt salt on a fluorine-doped oxide( FTO) glass substrate. The photo-current density-voltage( J-V) curves show that the overall energy conversion efficiency of DSSC with the Pt/Ti counter electrode increases by 20. 8% relative to that with the Pt/FTO counter electrode. The results also re-veal that the improved performance of the DSSC with the Pt/Ti counter electrode is assigned to the higher elec-trochemical surface area of the Pt/Ti counter electrode than the Pt/FTO, the lower electric resistance and the better reflecting ability of the Ti substrate than the FTO substrate.
