Researchers from Philips, Graphenea and the University of Cambridge developed a new graphene-based transparent electrode that outperforms ITO in OLED lighting panels. . Graphene by itself is not a good electrode material because the concentration of the charge carriers is low – which means that you need to dope it with excess carriers – while leaving it flexible and transparent. To achieve that, the team used a metal oxide film (molybdenum trioxide, MoO 3 ) as an intermediate layer between the graphene and the OLED layers. The work was performed as part of the EU project GRAFOL, aimed at roll-to-roll mass production of graphene.
