| Abstract: | 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). |
