摘要：

In this paper, an organic photovoltaic device based on an acceptor of solution-processable functionalized graphene was designed. A short circuit current density (J(sc)) of 4.0 mA cm(-2), open circuit voltage (V-oc) of 0.72 V, and a solar power conversion efficiency of 1.1% were obtained for the device of indium tin oxide/poly(ethylene dioxythiophene) doped with polystyrene sulfonic acid (40 nm)/poly(3-hexylthiophene-1, 3-diyl):graphene (graphene 10 wt %, 100 nm)/LiF (1 nm)/Al (70 nm) after an annealing treatment under simulated AM1.5G 100 mW illumination in air. Because of the low price, ease of preparation, and inertness against ambient conditions, soluble graphene will be a promising candidate used for acceptor materials in the photovoltaic applications.
