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:PC71 BM single-junction PSCs. A PCE of 8.6% is achieved when a C-PCBSD cathodic interlayer is introduced.enbulk-heterojunction organic photovoltaics; conjugated polymers; fullerenes; organic electronics; porphyrinjournal article10.1002/adma.201401345248901832-s2.0-84905856150https://api.elsevier.com/content/abstract/scopus_id/84905856150
