摘要：

Dye-sensitized solar cells using quaternary phosphomurn ionic liquids as their electrolytes have been successfully fabricated. Of these, the best device performance was achieved by using triethyl(pentyl)phosphonium bis(trifluoromethyl-sulfonyl)amide, whose energy conversion efficiencies were determined to be 1.2% and 3.8% under full (AM 1.5, 100 mW cm(-2)) and low intensity (7 MW cm(-2)) sunlight illumination, respectively. Interestingly, the energy conversion efficiencies for the quaternary phosphonium ionic liquid electrolytes are higher than those for the corresponding quaternary ammonium ionic liquids.
