Researchers from the UK's University of Exeter discovered a new graphene based material that can be used as an ITO replacement. The so-called GraphExeter is a lightweight, flexible and transparent conductor which is more flexible than ITO and will hopefully be cheaper.
GraphExeter is made by compressed ferric chloride molecules between two sheets of graphene. The researcher are also working on a spray-on version of the material. This is not the first graphene based ITO replacement material. Back in August Rice University researchers unveiled a hybrid metal-graphene electrode which can also relace ITO.
