Provided are an additive for an electrolytic composition which can suppress the decrease of a short-circuit current and improve an open circuit voltage as compared to the case when conventional 4-TBpy is used as an additive for an electrolytic composition, and an electrolytic composition using this additive and a dye-sensitized solar cell. The additive for an electrolytic composition for use in a dye-sensitized solar cell contains a pyridine derivative having a pyridine ring into which an alkylsilyl group is introduced, and it is preferable that this pyridine derivative has an alkylsilyl group at the 4-position of the pyridine ring, and it is more preferable that the pyridine derivative is 4-(trimethylsilyl) pyridine.
