【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时电极铂金含量较低；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%．更多还原

【Abstract】 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%.更多还原
