Abstract: A series of linear acceptor-donor-acceptor (A-D-A) small-molecule organic solar cell materials OVFFBT, OVFBT and OVFPT, which were composed of 9-methylfluorine as donor and benzo[1,2,5]thiadiazole, 5-fluorobenzo[1,2,5]thiadiazole and [1,2,5]thiadiazolo[3,4-c]pyridine as acceptors, were designed and synthesized. We found that optical properties, electrochemical properties and device performances of the resulting materials were strongly influenced by the acceptor units. The photovoltaic properties based on OVFFBT, OVFBT and OVFPT as donors and [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) as the acceptor were investigated with a conventional device structure of ITO/PEDOT:PSS/Active layer/Al. The device based on OVFFBT and PC61BM exhibited high open-circuit voltage approaching 1.0 V.
