4.2.3 Improving the Conductivity of Graphene-Based
Transparent Electrode
The high sheet resistance is one of the most important factors for the poor
performance of organic electronic devices employing transparent electrodes based
on graphene. A strategy to improve the conductivity of the graphene films is to
