A fluorinated ionic liquid (FIL) has been used as a source of iodide ions in solvent based electrolytes for DSSCs. The FIL improves the charge transfer dynamics at the TiO2-dye/electrolyte interface and the transport in the electrolyte solution.

ABSTRACT
We report on the use of a fluorinated imidazolium ionic liquid as a source of iodide ions in solvent-based electrolytes for DSSCs. Efficient dye regeneration and fast charge transport in the fluorinated electrolyte result in an overall improvement of the device performances compared to conventional hydrogenated ionic liquids.
