A series of organic thiolate/disulfide redox couples have been synthesized and have been studied systematically in dye-sensitized solar cells (DSCs) on the basis of an organic dye (TH305). Photophysical, photoelectrochemical, and photovoltaic measurements were performed in order to get insights into the effects of different redox couples on the performance of DSCs. The polymeric, organic poly(3,4-
已经合成了一系列有机硫醇盐/二硫化物氧化还原对,并在有机染料 (TH305) 的基础上在染料敏化太阳能电池 (DSC) 中进行了系统研究。进行了光物理、光电化学和光伏测量,以深入了解不同氧化还原对对 DSC 性能的影响。聚合物有机聚(3,4-亚乙基二氧噻吩)(PEDOT)材料也已被引入这种不含碘的 DSC 中作为对电极,在 AM 1.5G、100 mW·cm(- 2)灯光照明。使用电化学阻抗谱和线性扫描伏安法的详细研究表明,与常用的镀铂导电玻璃电极相比,PEDOT 对电极表面上二硫化物的还原效率更高。已经在 DSC 中研究了基于硫醇盐阴离子的纯离子液体电解质和溶剂化离子液体电解质。含有有机氧化还原对的纯和溶剂化离子液体基电解质在 10 mW·cm(-2) 光照下分别呈现 3.4%和 1.2% 的效率。
