Porphyrin-Incorporated 2D D-A Polymers with Over 8.5% Polymer Solar Cell Efficiency

Porphyrin-Incorporated 2D D-A Polymers with Over 8.5% Polymer Solar Cell Efficiency

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 (Jsc) without sacrificing the open‐circuit voltage (Voc) and fill factor (FF)...

Zusammenfassung: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 (Jsc) without sacrificing the open‐circuit voltage (Voc) and fill factor (FF). Up to 8.0% power conversion efficiency (PCE) is delivered by PPor‐2:PC71BM single‐junction PSCs. A PCE of 8.6% is achieved when a C‐PCBSD cathodic interlayer is introduced.
