A copolymerization strategy is developed to utilize porphyrin as a complementary light‐harvesting unit (LHU) in D–A polymers. For polymer solar cells (PSCs), the presence of LHUs increases the short‐circuit current density (J sc ) without sacrificing the open‐circuit voltage (V oc ) and fill factor (FF). Up to 8.0% power conversion efficiency (PCE) is delivered by PPor‐2:PC 71 BM single‐junction PSCs. A PCE of 8.6% is achieved when a C‐PCBSD cathodic interlayer is introduced.
