利用超微铂电极和循环伏安法, 以及电化学阻抗谱研究了在1-甲基-3-己基咪唑碘(HMII)的3-甲氧基丙腈(MePN)溶液中I3－和I－的氧化还原行为, 并对比了由不同浓度的I2和HMII组成的电解质溶液对染料敏化纳米薄膜太阳电池(DSCs)光伏性能的影响. 发现以MePN为溶剂, 含1.0 mol•dm－3 HMII, 0.12 mol•dm－3 I2, 0.10 mol•dm－3 LiI和0.50 mol•dm－3 4-叔丁基吡啶的电解质溶液, 其DSCs的短路光电流密度为14.06 mA•cm－2, 开路电压为0.71 V, 填充因子为0.69, 光电转换效率达6.81%.

In this paper, redox behavior of I－ and I3－ in 3-methoxypropionitrile (MePN) with different concentrations of 3-hexyl-1-methylimidazolium iodide (HMII) and iodine was investigated by cyclic voltammetry and electrochemical impedance spectroscopy. The photovoltaic performance of dye-sensitized solar cells (DSC) was compared for electrolytes containing different concentrations of HMII and iodine. The DSC with the electrolyte (1.0 mol•L－1 HMII, 0.10 mol•L－1 LiI, 0.12 mol•L－1 I2 and 0.50 mol•L－1 4-tert-butylpyridine in MePN) gave short circuit photocurrent density Jsc of 14.06 mA•cm－2, open circuit voltage Voc of 0.71 V, and fill factor FF of 0.69, corresponding with the photoelectric conversion efficiency η of 6.81% under one Sun (Xenon lamp, AM1.5, 100 mW/cm2).
