Swedish researchers from Linköping and Umeå universities have collaborated with American researchers to develop a new graphene-based, energy-saving, transparent electrode that could impart a green illumination to wallpaper and ceilings. The electrodes are founded on organic light-emitting electrochemical cells (or LECs) that are actually large, flexible sheets. The entire process of producing these electrodes promises to be extremely cost-effective, thanks to the LEC technology. Moreover, it’s easier to recycle the metal-free LEC as fuel.
By using graphene instead of conventional metal electrodes, components of the future will be much easier to recycle and thereby environmentally attractive.
Says Nathaniel Robinson from Linköping University.
