1. A composition containing a polymer having a structural unit represented by the following formula (1) and a structural unit represented by the following formula (2), and a fullerene derivative having a fullerene skeleton with a carbon number of 70 or more:wherein in the formulae (1) and (2), Q, R, R1 and R2 each independently denote a hydrogen atom, a fluorine atom, an alkyl group with a carbon number of 1 to 20, an alkoxy group with a carbon number of 1 to 20, or an optionally substituted aryl group with a carbon number of 6 to 60, wherein, a part or all of hydrogen atoms in the alkyl group with a carbon number of 1 to 20, the alkoxy group with a carbon number of 1 to 20, and the optionally substituted aryl group with a carbon number of 6 to 60 may be substituted with fluorine atoms, R1 and R2 may be bonded together to form a ring, and Q's and R's may be the same or different; and the fullerene derivative having a fullerene skeleton with a carbon number of 70 or more is selected from the group consisting of the following formulae:where A denotes a fullerene skeleton with a carbon number of 70 or more and in a fullerene derivative represented by each of the formulae, two adjacent carbon atoms in the fullerene skeleton form a cyclopropane ring or a pyrrolidine ring together with atoms in an additional group. |
