Abstract
A composition which comprises a conjugated polymer, a fullerene derivative, a first solvent, and a second solvent. When the sum of the weight of the first solvent and the weight of the second solvent is taken as 100, the weight of the first solvent is 70-97. The first solvent at 25° C. has a surface tension exceeding 25 mN/m, and the second solvent at 25° C. has a surface tension of 15-25 mN/m.
