ITO is the most common transparent conducting material used today because of its high electrical conductivity, high optical transparency and ease of deposition. ITO is currently used in a huge range of applications, e. g. solar cells, displays, touch panels, smart watches, etc. More than 90% of the display market uses ITO. However, Indium is expensive and scarce.  Repacing ITO with graphene is therefore a hugh market opportunity. This project will explore replacing ITO with graphene in a number of devices including organic light emitting diodes (OLEDs).
