Investigation on Applying Compound Solvent in Liquid Electrolyte for Dye-Sensitized Solar Cells
Liquid electrolyte for dye-sensitized solar cells (DSSCs) was prepared by using the mixture of sulfolane and 3-methoxypropionitrile as a solvent, 4-tert-butylpyridine as an additive. The influences of sulfolane on electrolyte conductivity, photoelectric performances and the DSSCs stability were investigated. The results indicated that when the ratio of 3-methoxypropionitrile to sulfolane achieves 3:2, the cell showed the optimal photoelectric properties and stability, and the short-circuit current and photoelectric conversion efficiency achieved 7.58mA/cm2 and 2.79%, respectively.
