Graphene oxide (GO) is an atomically thin carbon nanostructure with various oxygen-containing functional moieties such as carbonyl, carboxyl, and hydroxyl. GO and rGO have attracted a great deal of attention due to their remarkable physical, chemical, and mechanical properties and could be used as a potential novel electronic material.
Graphene oxide (GO) is potentially usable due to its simple synthesis and processing. The presence of oxygen functional groups leads to dispersibility in water and other organic solvents. This remains a very important feature for improving their properties of the material with polymer matrixes such as electrical and mechanical characterization. From previous studies in the literature, it is known that in graphene one absorbed photon is capable of producing many excited electrons (in traditional materials, energy from one photon only excites one electron) and is, therefore, able to drive a greater photocurrent. Due to the very low level of light absorption and concurrently high electron mobility of graphene, this material can be used as an alternative to ITO in the interlayer of photovoltaic cells.
Graphene oxide (GO) is often described as an electrical insulator due to the disruption of its bonding networks. The relationship between the structure and properties of GO and rGO films can be assessed by the characterization of its oxidation degree. This can be done by the evaluation of the carbon fraction since the optical and electrical properties are mostly governed by the π-electrons from carbon atoms.
