研究了对电极上涂覆的 Pt 薄膜的厚度和形貌对染料敏化太阳能电池（DSC）性能的影响。沉积厚度范围为2至415 nm的Pt膜会逐渐降低对电极的薄层电阻。对于 25 至 415 nm 范围内的 Pt 膜厚度，没有观察到电解质 I 对电极界面处的电荷转移电阻存在显着差异。基于具有 2 nm 极薄 Pt 膜以及 415 nm 厚 Pt 膜的对电极的 DSC 可以获得约 5% 的高能量转换效率。这些结果对于通过减少昂贵铂金的需求量来降低生产成本非常重要。 (C) 2004 Elsevier B.V. 保留所有权利。
The effects of the thickness and morphology of a Pt film coated on a counter electrode on the performance of a dye-sensitized solar cell (DSC) were investigated. Deposition of a Pt film ranging in thickness from 2 to 415 nm gradually decreases the sheet resistance of the counter electrode. No significant difference in the charge-transfer resistance at the electrolyte I counter electrode interface was observed for a Pt film thickness ranging from 25 to 415 nm. A high energy conversion efficiency of approximately 5% can be obtained for DSCs based on a counter electrode with a very thin Pt film of 2 nm, as well as with a 415-nm thick Pt film. These results are important for reducing production costs by reducing the required amount of expensive platinum. (C) 2004 Elsevier B.V. All rights reserved.
