We report the synthesis of a solution-processable, dodecyloxyphenyl-substituted azafullerene monoadduct (DPC59N) and its application as electron acceptor in bulk heterojunction organic solar cells (BHJ-OSCs). Due to relatively strong absorption visible light, DPC59N outperforms PC60BM respect short circuit current (JSC) external quantum efficiency (EQE) blends with donor P3HT.
