Abstract:
An object of the present invention is to provide an electrolyte for photoelectric conversion elements, and a photoelectric conversion element and a dye-sensitized solar cell using the electrolyte, wherein high energy conversion efficiency can be achieved while substantially not including iodine. The electrolyte for a photoelectric conversion element of the present invention includes an ionic liquid (A) and a carbon material (B). The carbon material (B) is a carbon material (B1) displaying a pH, measured by a pH measuring method specified in Japanese Industry Standard (JIS) Z8802, of from 2 to 6 and/or a boron-modified acetylene black (B2). A content of the carbon material (B) is from 10 to 50 parts by mass per 100 parts by mass of the ionic liquid (A).
