Graphene, as a multifunctional two-dimensional nanomaterial, has inspired the considerable interests on its application in novel nanodevices. In this paper, the optoelectronic function of the complexes of typical semiconductors and graphene was reviewed based on the graphene's advantages of transmission, flexibility, turnable energy bandgap, and high electron mobility. It presented the representative application of graphene in inorganic and organic light-emitting diodes, solar cells, and nanogenerators. It is expected that graphene would play an important role for further nanometer sized electronic and photonic devices in the post-Mole era.
