The exciting features in almost all modern portable and house-hold electronics are driven by optoelectronics that extensively use transparent conductive films (TCFs) in components, such as touch screens, liquid crystal displays, organic photovoltaic cells and organic light-emitting diodes. Because of its excellent electrical conductivity, optical transparency and mechanical properties, graphene has been considered an ideal material to replace the existing, expensive indium tin oxide (ITO) as TCFs. Graphene oxide (GO) in the form of colloidal suspension is not only scalable for high volume production at low costs, but also compatible with emerging technologies based on flexible substrates. This paper reviews the current state-of-the-art developments and future prospects of TCFs synthesized using GO suspension. In addition, several established approaches are introduced, which have been proven effective in improving the optoelectrical performance of GO-based TCFs. They include chemical doping treatments, use of large size GO sheets, and hybrids with other nanostructured materials, such as carbon nanotubes (CNTs), metal nanowires (NWs) or nanogrids. © 2014 Elsevier Ltd.
