本文报道了一种快速（5 min），低温（120 °C）的方法来镀化染料敏化太阳能电池（DSC）器件的对电极。这种新方法使用水溶液，是基于化学浴沉积的激活Pd层，然后是Pt层，只使用H2gas作为还原剂。该方法已在柔性塑料衬底上进行了测试（分别为氧化铟锡涂层的聚对苯二甲酸乙二醇酯或聚萘二甲酸乙二醇酯，ITO-PET或ITO-PEN）。我们报告ITO-PET上的设备效率高达7.2%，与使用高温（400 °C）处理刚性，掺氟氧化锡（FTO）玻璃对电极制成的设备相当。该方法具有可扩展性，适用于连续卷对卷生产。
This paper reports a rapid (5 min), low temperature (120 °C) method to platinize the counter electrodes of dye-sensitized solar cell (DSC) devices. This new method uses aqueous solutions and is based on chemical bath deposition of an activating Pd layer followed by Pt only using H2gas as the reductant. This method has been tested on flexible, plastic substrates (indium tin oxide-coated polyethylene terephthalate or polyethylene naphthalate, ITO-PET or ITO-PEN, respectively). We report device efficiencies up to 7.2% on ITO-PET which is comparable to devices made using high temperature (400 °C) processing on rigid, fluoride-doped tin oxide (FTO) glass counter electrodes. The method is scalable and suitable for continuous roll-to-roll production.
