摘要: 采用季铵化反应合成了1-丁基-3-甲基咪唑碘([Bmim]I).以此制备了DSCs用液体电解质.通过对比不同浓度的1-丁基-3-甲基咪唑碘、碘化钾、碘,研究其对电池性能的影响.经过优化后,当cIL=0.9 mol·L-1、cKI=0.5 mol·L-1、cI2=0.12 mol·L-1时,所组装的离子液体DSCs在AM1.5,100 mW·cm-2下,DSCs的短路电流密度为15.97 mA·cm-2、开路电压为0.71 V、填充因子为0.55、光电转换效率可达6.34%.

Abstract: 1-Butyl-3-methylimidazolium iodide was synthesized by quaternization.The photovoltaic performance of dye-sensitized solar cells (DSCs) was compared for electrolytes containing different concentrations of I,KI and iodine.After optizimed,the DSCs with the electrolyte (0.90 mol·L-1 I,0.50 mol·L-1 KI and 0.12 mol·L-1 I2 in GBL) gave short circuit photocurrent density (Jsc) of 15.97 mA·cm-2,open circuit voltage (Voc) of 0.71 V,and fill factor (FF) of 0.55,corresponding with the photoelectric conversion efficiency (η) of 6.34% under one Sun (Xenon lamp,AM1.5,100 mW·cm-2).
