The woven fabric containing electrochemically platinized tungsten wire is an affordable flexible cathode for liquid-junction dye-sensitized solar cells with the I3(-)/I(-) redox mediator and electrolyte solution consisting of ionic liquids and propionitrile. The fabric-based electrode outperforms the thermally platinized FTO in serial ohmic resistance and charge-transfer resistance for triiodide reduction, and it offers comparable or better optical transparency in the visible and particularly in the near-IR spectral region. The electrode exhibits good stability during electrochemical loading and storage at open circuit. The dye-sensitized solar cells with a C101-sensitized titania photoanode and either Pt-W/PEN or Pt-FTO cathodes show a comparable performance.
含有电化学镀铂钨丝的织物是一种价格实惠的柔性阴极，用于带有I3(-)/I(-)氧化还原介质以及由离子液体和丙腈组成的电解质溶液的液接染料敏化太阳能电池。这种基于织物的电极在串联欧姆电阻和三碘化物还原的电荷转移电阻方面优于热镀铂的FTO，并且在可见光特别是近红外光谱区域具有相当或更好的光学透明度。该电极在开路状态下的电化学负载和存储过程中表现出良好的稳定性。具有C101敏化二氧化钛光阳极以及Pt-W/PEN或Pt-FTO阴极的染料敏化太阳能电池表现出相当的性能。
