Ternary polymer solar cells are fabricated based on one donor PBDB‐T and two acceptors (a methyl‐modified small‐molecular acceptor (IT‐M) and a bis‐adduct of Bis[70]PCBM). A high power conversion efficiency of 12.2% can be achieved. The photovoltaic performance of the ternary polymer solar cells is not sensitive to the composition of the blend.
