Transparent Graphene Electrodes

A new method of making large sheets of high-quality, atomically thin graphene could lead to ultra-lightweight, flexible solar cells and to new classes of light-emitting devices and other thin-film electronics. The manufacturing process involves an intermediate “buffer” layer of material that allows the ultrathin graphene sheet, less than a nanometer (billionth of a meter) thick, to be easily lifted off from its substrate, allowing for rapid roll-to-roll manufacturing.
