A systematic study is conducted to compare the performances and stability of active layers employing a high performance electron donor (PBDB‐T) combined with state‐of‐the‐art fullerene (PC71BM), nonfullerene (ITIC), and polymer (N2200) electron acceptors. The impact of the chemical nature of the acc...
