PROBLEM TO BE SOLVED: To provide a fullerene derivative which has high solubility in an organic solvent and is capable of achieving high photoelectric conversion efficiency.SOLUTION: The ≥60C fullerene derivative has one or more structures represented by general formula (I). (In the formula, R, R, and Reach independently represent a hydrogen atom, a halogen atom, an optionally substituted alkyl group, an optionally substituted alkoxy group, an optionally substituted aryl group, or an optionally substituted monovalent heterocyclic group, and at least one of R, R, and Rcontains either a structure of an alkoxycarbonyl group which has an optionally substituted 4-30C alkyl group or the like, or a hydroxyl group.) |
