An organic ionic plastic crystal, 1-ethyl-1-methylpyrrolidinium bis(trifluoromethanesulfonyl) imide (P12TFSI), was synthesized and doped with a room temperature ionic liquid, 1-propyl-3-methylimidazolium iodide (PMII). The prepared PMII/P12TFSI solid-state electrolytes were employed for dye-sensitized solar cells (DSSCs), without using any volatile organic solvent. The fabricated solid-state DSSCs yielded a power conversion efficiency of 5.12% under simulated air mass 1.5 solar spectrum illuminations at 50 mW cm−2. The superior long-term stability of the fabricated solid-state DSSCs indicated that the synthesized PMII/P12TFSI solid-state electrolytes could overcome the drawbacks of cells containing volatile solvents.
合成了一种有机离子塑料晶体--1-乙基-1-甲基吡咯烷鎓双(三氟甲磺酰基)亚胺(P12TFSI),并在其中掺杂了一种室温离子液体--1-丙基-3-甲基碘化咪唑鎓(PMII)。制备的 PMII/P12TFSI 固态电解质被用于染料敏化太阳能电池(DSSC),无需使用任何挥发性有机溶剂。所制备的固态 DSSC 在 50 mW cm-2 的模拟空气质量 1.5 太阳光谱照射下的功率转换效率为 5.12%。所制备的固态 DSSC 具有优异的长期稳定性,这表明合成的 PMII/P12TFSI 固态电解质可以克服含有挥发性溶剂的电池的缺点。
