染料敏化太阳能电池的阻抗分析在三电极电池中通过使用玻璃容器来分离归因于工作电极和对电极的阻抗来进行。当工作电极和对电极之间的距离增加时，电池的总阻抗不受此参数的影响，尽管溶剂电阻和扩散层的厚度随着电极之间的距离而增加。各种类型的铂反电极用于三电极装置的阻抗测量。小表面积的对电极导致对电极的阻抗谱中的大弧，而当对电极的表面积减小时，TiO 2-工作电极的阻抗谱没有显示出差异。这些结果表明，使用三电极玻璃容器型染料敏化太阳能电池的阻抗测量适合于分离归因于工作电极和对电极的阻抗。(c)2004 Elsevier B. V.保留所有权利。
Impedance analysis for dye-sensitized solar cells was carried out in a three-electrode cell by using a glass vessel to separate the impedances attributable to the working electrode and the counter electrode. When the distance between the working and counter electrodes increased, the overall impedance of the cells was not affected by this parameter, although the solvent resistance and the thickness of the diffusion layer was increased with the distance between the electrodes. Various kinds of Pt counter electrodes were used for impedance measurement with the three-electrode set-up. Counter electrodes of small surface area resulted in a large arc in the impedance spectra of the counter electrodes, whereas the impedance spectra of the TiO2-Working electrodes showed no differences when the surface area of the counter electrode was decreased. These results suggested that the impedance measurement using a three-electrode glass vessel type dye-sensitized solar cell was suitable to separate the impedances attributed to the working and counter electrodes.
