The influence of fullerene derivatives (PC 60 BM and PC 70 BM) and processing additives on the molecular order of a naphthobisthiadiazole‐based polymer (NT) in the blend films differ significantly. This is strongly associated with the bulk heterojunction (BHJ) solar cell performance and affects charge recombination rates and sweep‐out dynamics.
