Abstract

We report on the application of a poly(methyl acrylate)/poly(ethylene glycol)-based polymer gel electrolyte and triphenylamine-based metal-free organic dyes in quasi-solid-state dye-sensitized solar cells. The poly(methyl acrylate)/poly(ethylene glycol) hybrid is beneficial to the entrapment of a large volume of liquid electrolyte. At 25 degrees C, the ionic conductivity and the triiodide ionic diffusion constant of the as-prepared polymer gel electrolyte are 2.1 mS cm(-1) and 2.3 x 10(-6) cm(2) s(-1), respectively. The quasi-solid-state solar cell sensitized by triphenylamine-based dyes attains an overall energy conversion efficiency of 5.76% at a light intensity of 30 mW cm(-2). The presence of poly(ethylene glycol) in the electrolyte obviously increases the conductivity and energy conversion efficiency compared to that without poly(ethylene glycol).

摘要

我们报告了一种基于聚甲基丙烯酸酯/聚乙二醇的聚合物凝胶电解质和三苯胺基无金属有机染料在准固态染料敏化太阳能电池中的应用。聚甲基丙烯酸酯/聚乙二醇杂化有利于捕获大量的液体电解质。在 25°C 下，所制备的聚合物凝胶电解质的离子电导率和三碘离子扩散常数分别为 2.1 mS cm(-1)和 2.3 x 10(-6) cm(2) s(-1)。由三苯胺基染料敏化的准固态太阳能电池在 30 mW cm(-2)的光强下获得了 5.76%的整体能量转换效率。与不含聚乙二醇的电解质相比，电解质中存在聚乙二醇明显提高了电导率和能量转换效率。
