A highly efficient acceptor material for organic solar cells (OSCs) – based on perylene diimide (PDI) dimers – shows significantly reduced aggregation compared to monomeric PDI. The dimeric PDI shows a best power conversion efficiency (PCE) approximately 300 times that of the monomeric PDI when blended with a conjugate polymer (BDTTTT‐C‐T) and with 1,8‐diiodooctane as co‐solvent (5%). This shows that non‐fullerene materials also hold promise for efficient OSCs.
