A nonfullerene‐based polymer solar cell (PSC) that significantly outperforms fullerene‐based PSCs with respect to the power‐conversion efficiency is demonstrated for the first time. An efficiency of >11%, which is among the top values in the PSC field, and excellent thermal stability is obtained using PBDB‐T and ITIC as donor and acceptor, respectively.
