Graphene-based transparent touchscreens and solar panels a step closer

Graphene-based transparent touchscreens and solar panels a step closer: "Graphene promises to revolutionize electronics but we're still waiting for graphene-based technologies to hit the market. Rice University researchers have now created transparent, graphene-based electrodes that they say could be the 'killer app' that finally puts graphene into the commercial spotlight. The graphene-based electrodes could be used to replace the increasingly expensive indium tin oxide (ITO) in touch-screen displays, photovoltaic solar cells and LED lighting."
