Abstract
Graphene is an excellent material for transparent conductive electrodes due to its high electrical conductivity, transparency, flexibility, and mechanical strength. On the other hand silver nanowires (AgNWs) have also been considered as an excellent material for transparent conductive electrodes due to their high electrical conductivity, high aspect ratio, good transparency and other properties suitable for transparent electronics. Herein, we have presented a simple approach to combine the properties of graphene and silver nanowires to develop a good transparent and flexible conductive electrode on polyethylene terephthalate (PET) sheet. The transmittance of the as-prepared graphene/AgNWs electrode was found to be 82.6% at 550 nm, which is comparable to the transmittance of commercial transparent conductive electrodes. The sheet resistance of the electrode was determined to be 212.59 kΩ/sq (measured by four point-probe method). The low sheet resistance of the graphene/AgNW electrode makes it suitable for use in a variety of electronic devices, including solar cells, supercapacitors, flexible displays, and touch sensitive screens. The proposed approach is highly scalable and can boost the fabrication of low cost and highly transparent electrodes.
