A gold nanoparticles transparent electrode was realized by chemical reduction. This work aims to compare the transparent gold nanoparticles electrode with a more commonly utilized gold-film-coated electrode in order to investigate its potential use as counter-electrode (CE) in dye-sensitized solar cells (DSSCs). A series of DSSC devices, utilizing I/I and Co(III)/(II) polypyridine redox mediators [Co(dtb)3]/; dtb = 4,4'ditert-butyl-2,2'-bipyridine)], were evaluated. The investigation focused firstly on the structural characterization of the deposited gold layers and then on the electrochemical study. The novelty of the work is the realization of a gold nanoparticles CE that reached 80% of average visible transmittance. We finally examined the performance of the transparent gold nanoparticles CE in DSSC devices. A maximum power conversion efficiency (PCE) of 4.56% was obtained with a commercial I/I-based electrolyte, while a maximum 3.1% of PCE was obtained with the homemade Co-based electrolyte.
通过化学还原制备了金纳米颗粒透明电极。这项工作旨在将透明金纳米颗粒电极与更常用的金膜涂覆电极进行比较，以研究其在染料敏化太阳能电池（DSSC）中作为对电极（CE）的潜在用途。评估了一系列使用I/I和Co(III)/(II)多吡啶氧化还原介质[Co(dtb)3]/；dtb = 4,4'-二叔丁基-2,2'-联吡啶]的DSSC器件。研究首先集中在沉积金层的结构表征上，然后进行电化学研究。这项工作的新颖之处在于实现了平均可见光透射率达到80%的金纳米颗粒对电极。我们最终研究了透明金纳米颗粒对电极在DSSC器件中的性能。使用基于I/I的商业电解质时，获得了4.56%的最大功率转换效率（PCE），而使用自制的基于Co的电解质时，获得了最高3.1%的PCE。
