Submission + - Nanowires Improve Graphene Conductance (acs.org)

MTorrice writes: "Researchers may have found a way to turn one-atom-thick sheets of graphene into a promising material for making transparent electrodes needed in solar cells and displays. Transparent electrodes in today’s devices are made of indium tin oxide films. These films are typically 90% transparent and have a resistance of less than 100 ohms. But they are expensive and brittle. Graphene could be a stronger, lower-cost, and more bendable alternative. However, the resistance of a typical graphene sheet is usually more than 500 ohms. By integrating metal nanowires into conventionally grown graphene films, researchers lowered the films’ resistance. The resulting material is 94% transparent and has a resistance of 64 ohms."
