In this work, a metal busbar microstructure is introduced to decrease the effective sheet resistance of both graphene and carbon nanotube films to a value suitable for use as transparent conducting electrodes (TCEs). The proposed busbar architecture, implemented with Cu, theoretically can reduce the...
