Abstract

Graphene is very attractive as a transparent conductive electrode (TCE) for the different optoelectronic devices due to its optical and electrical properties such as optical transparency, electron conductivity, and carrier mobility. In this work, a graphene layer is deposited from a suspended graphene solution to use it as TCE. The graphene was synthesized using the liquid phase exfoliation method and was dispersed in IPA, and spin-coated at n-Si substrate to form the graphene layer. The effect of spin coating speed was studied, and the optimum speed was found to be 3000 rpm, as it could decrease the reflectance of the bare Si substrate from an average of 41.7% to 16.6% in the visible range after coating it with graphene at 3000 rpm. A sheet resistance of 1.49×10², Ω/Sq was obtained for the deposited graphene layer. These results showed that the synthesized graphene has desired properties for of TCE application.
