Abstract

Determination of triiodide diffusion coefficient, charge-transfer resistance and photovoltaic performance of the binary ionic liquid electrolyte of 1-methyl-3-propylimidazolium iodide (MPII) and 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIMBF₄) for dye-sensitized solar cells (DSSCs) were performed at varying volume ratios of MPII/EMIMBF₄. Compared to pure MPII ionic liquid, the addition of EMIMBF₄ not only increased triiodide diffusion coefficient, but also decreased charge-transfer resistance at Pt/electrolyte interface, leading to the notably improved photovoltaic performance of DSSC. The highest photoelectric conversion efficiency of 4.99% was obtained under light intensity of 100 mW/cm² for the DSSC with the binary MPII/EMIMBF₄ ionic liquid electrolyte when the volume ratio of MPII/EMIMBF₄ was 50/50, which was much higher than that of pure MPII ionic liquid electrolyte (2.6%).
