Application
Monomer for synthesis of polymers for high power conversion efficiency (PCE) organic solar cells and high mobility OFETs.
Fluorination lowers the polymer HOMO level; resulting in high open-circuit voltages well exceeding 0.7 V.

A novel fluorinated copolymer (F-PCPDTBT) is introduced and shown to exhibit significantly higher power conversion efficiency in bulk heterojunction solar cells with PC(70)BM compared to the well-known low-band-gap polymer PCPDTBT. Fluorination lowers the polymer HOMO level, resulting in high open-circuit

Small band-gap conjugated polymers based on monofluoro- and difluoro-substituted benzothiadiazole were developed. Highly efficient polymer solar cells (PCE as high as 5.40%) could be achieved for devices made from these polymers.
