摘　　要：分别采用了3种不同的方法制备了用于染料敏化TiO2太阳电池的铂金对电极，并分别以此3种铂金对电极组装染料敏化太阳电池，对比、分析和探讨了它们对光电转化性能的影响。结果表明：采用纳米粒子电沉积法与电化学电镀法制备的铂金对电极，具有较高的催化活性，以这两种方法制备的铂金对电极组装的DSSCs获得较好的光电转化性能，电池的光电转化效率分别为6．40％和6．63％，且采用纳米粒子电沉积法制备的铂金对电极铂金含量较低；而采用热分解法制备的铂金对电极来组装的DSSCs获得的光电性能相对较低，电池效率为5．58％。Platinum counter electrodes were prepared by three different methods. The dye-sensitized solar cells were assembled with these platinum counter electrodes. The Effect on the Performance of Dye-Sensitized Solar Cell was studied and discussed. As a result, the Pt counter electrodes prepared by methods of nanoparticles electrodepositing and electroplating had better catalyzing performance for redox couples （I-I3）. And DSSCs assembled with these platinum counter electrodes exhibited higher photoelectric conversion efficiency （6.40 % and 6.63 %, respectively）. The photoelectric conversion efficiency of DSSCs assembled with the Pt counter electrodes prepared by thermal decomposition method was 5.58 %.
