Photovoltaic Properties of Poly[(9,9-dioctylfluorenyl-2,7-vinylene)-co-{2-(3'-dimethyldodecylsilylphenyl)-1,4-phenylenevinylene}] for Electro-Active Devices

摘要

New,thermally robust,arylenevinylene conjugated polymers,including poly(9,9-dioctylfluorenyl-2,7-vinylene) [poly(FV)] and poly[2-(3'-dimethyldodecylsilylphenyl)-1,4-phenylenevinylene] [poly(m-SiPhPV)],were synthesized and used for the fabrication of efficient photovoltaic cells.Bulk heterojunction photovoltaic cells fabricated by blending one of the polymers,[poly(FV)],[poly(m-SiPhPV)],and poly(FV-co-m-SiPhPV),with the fullerene derivative [6,6]-phenyl-C_(61)-butyric acid methyl ester (PCBM) were found to have a power conversion efficiency of up to 0.038%.
