| Abstract: | The redox behaviors of I－ and I3－ in 3-methoxypropionitrile (MePN) with different concentrations of 1,2-dimethyl-3-propylimidazolium iodide (DMPII) and iodine were investigated by cyclic voltammetry and electrochemical impedance spectroscopy. The photovoltaic performance of dye-sensitized solar cells (DSCs) was compared with electrolytes containing different concentrations of DMPII and iodine. The DSCs with the electrolyte (1.0 mol•dm-3 DMPII, 0.10 mol•dm-3 LiI, 0.12 mol•dm-3 I2, 0.50 mol•dm-3 4-tert-butylpyridine, in MePN) gave short circuit photocurrent density (Jsc) of 16.76 mA•cm-3, open circuit voltage (Voc) of 0.69 V, and fill factor (FF) of 0.70, corresponding to a photoelectric conversion efficiency (η) of 8.08% under one Sun (AM1.5). |
