Abstract
P3HT/PC(61)BM bulk heterojunction solar cells containing varying amounts of different 6,6-dicyanofulvenes (DCFs) were fabricated and characterized. Photovoltaic cells containing ternary mixtures of P3HT, 0.5 equiv of PC(61)BM, and 0.5 equiv of 1,4-dimethyl-2,3-diphenyl-DCF (by weight) displayed average power conversion efficiencies of up to 4.5% under AM 1.5 irradiation, compared to 2.9% for reference P3HT-PC(61)BM solar cells. It was found that 1,4-dimethyl-2,3-diphenyl-6,6-dicyanofulvene could replace up to 50 wt % of PC(61)BM in 1:1 P3HT-PC(61)BM solar cells without sacrificing device performance.
