摘要	We report the preparation and application of a 1-methyl-3-propylimidazolium sulfide-based ionic liquid electrolyte for quantum-dot-sensitized solar cells. By optimizing the concentrations of S and Na2S, a considerable conductivity of 12.96 mS.cm(-1) is achieved at 25 degrees C. Differential scanning calorimetry indicates that the glass transition temperature of the electrolyte is -85 degrees C. The quantum-dot-sensitized solar cell assembled with this ionic liquid electrolyte displays a high energy conversion efficiency (eta) of 3.03% at 25 C, which is comparable to the efficiency of quantum-dot-sensitized solar cells using a water-based polysulfide electrolyte (q = 3.34%). Due to the favorable thermal properties of this ionic liquid electrolyte (lower glass transition temperature and nonvolatility at higher temperatures), the quantum-dot-sensitized solar cell maintains satisfactory eta even at -20 degrees C (eta = 2.32%) and 80 degrees C (eta = 1.90%), which is superior to the cell using the water based polysulfide electrolyte.
