A star‐shaped porphyrin‐based molecule with four perylene bisimide arms (PBI‐Por) was designed as a non‐fullerene electron acceptor for application in solar cells. In their Communication on page 2694 ff., Z. Wang, W. Li, and co‐workers show that the combination of a donor polymer with PBI‐Por in a solar cell results in a photoresponse from λ =300 to 850 nm, with a maximum external quantum efficiency (EQE) of almost 0.70 and a promising power conversion efficiency of 7.4 %.
