Application of sulfonium ionic liquids in dye-sensitized nanocrystalline solar cells

S114TFSI and S221I ionic liquid is a kind of new room temperature ionic liquid, and has the advantages of high boiling point and less volatility , which make it capable of application in the Dye-sensitized solar cells. The performances of dye-sensitized solar cells with different thicknesses of electrodes, different volume percentages of S114TFSI/S221I and additions of additive such as TBP or LiI were measured. The tests show that the maximizing condition of the dye-sensitized solar cells is that the thickness of electrodes is 10 mm, the volume percentage of S221I is 50% and the concentrations of TBP and LiI are 0.5 mol/L and 0.2 mol/L.
