Graphene for Transparent Electrodes and Organic Electronic Devices

Abstract

Graphene has been regarded as a promising material in organic electronics owing to its outstanding electronic, optical, thermal, and mechanical properties. In this chapter, first, we summarize and discuss the application of graphene as transparent electrode in organic photovoltaic (OPV) cells and organic light emitting diodes (OLED). Improving the conductivity of graphene without compromising the transparency and tuning its work function to match the interface and/or active materials are proposed to focus on the future study for graphene-based transparent electrode. Then, the application of graphene as acceptor material in OPV has been addressed. The factors of size, energy level, and functionalization of graphene should be considered first. Last, graphene-based all-carbon electronics have been introduced, which indicates that graphene exhibits great potential for fabricating the highly demanded all-carbon, flexible devices and electronics.
