Photonic applications of graphene

Graphene can be used to enhance photonics, as a detector for light, an optoelectronic transceiver, or as part of high-resolution imaging systems. A surprising application of graphene is its use in photodetectors. Light detection capabilities of graphene are inherently limited because a single sheet of the material absorbs only ~2.3%...

Organic solar cells with graphene

Photovoltaic devices, or solar cells, are a means of generating electricity from sunlight in an environmentally friendly manner without emissions. Among the various types of solar cells, organic photovoltaics (OPVs) are known as lightweight, transparent, thin and flexible solutions. OPVs generally consist of a charge donor layer, a charge acceptor...
