Abstract

Dye sensitized solar cells (DSSCs) receive lots of attention as a suitable device in converting sunlight to electricity. A great deal of work has been carried out to develop gel polymer electrolytes (GPEs) and one strategy is introducing ionic liquids (ILs) to eliminate some adverse effects and also to improve ionic conductivity. The composition 15% polyvinylidene fluoride (PVdF): 37% ethylene carbonate (EC): 37% propylene carbonate (PC): 11% 1 butyl 3 methyl immidazolium iodide (IB 3M II) showed the highest conductivity. It was a good anionic conductor. IL has caused reduction of crystallinity which assists to enhance conductivity.

用于染料敏化太阳能电池的离子液体基凝胶聚合物电解质的阻抗谱、直流极化、XRD和SEM研究

染料敏化太阳能电池（DSSC）作为一种将阳光转化为电能的合适设备受到了广泛的关注。已经进行了大量的工作来开发凝胶聚合物电解质（GPE），其中一种策略是引入离子液体（ILs）来消除一些不利影响并提高离子电导率。15%的聚偏二氟乙烯（PVdF）:37%的碳酸亚乙酯（EC）:37%碳酸亚丙酯（PC）:11%1-丁基-3-甲基咪唑碘化物（IB 3M II）显示出最高的电导率。它是一种很好的阴离子导体。IL导致结晶度降低，这有助于提高导电性。
