Graphene-based Transparent Electrodes for Organic Electronics

1. Georgia Institute of Technology NSF MRSEC Highlight: Graphene-based Transparent Electrodes for Organic Electronics Samuel Graham, School of Mechanical Engineering, Georgia Tech Robert Haddon, School of Chemistry, University of California Riverside Dennis W. Hess, GA Tech Research Corporation - Georgia Institute of Technology, DMR 0820382 Fig. 2 Optical image showing the graphene oxide-carbon nanotube composite prior to annealing Before Annealing Fig. 3 Transparency data from the electrodes. This research is developing a low cost, solution processible transparent electrode for use in future flexible electronics. Recent results have suggested that the films will have properties which will surpass the currently used electrode in the electronics industry and will be applicable to a wide range of devices including solar cells and LEDs for next generation light sources.
