AbstractThanks to its high transparency, high carrier mobility, and thermal conductivity, graphene is often used as transparent conductive electrode (TCE) in optoelectronic devices. However, the low carrier concentration and high resistance caused by vacancy defects, grain boundaries, and superposed folds in typical graphene films limit its application. In this study, we propose a method to increase both the conductivity and carrier concentration in single-layer graphene (SLG) by blending it with silver nanowires (AgNWs). AgNWs provide connections between grain boundaries of graphene to improve charge-carrier transport. The AgNWs in this study can reduce the resistance of SLG from 650 Ω/◻ to 27 Ω/◻ yet still maintain a transmittance of 86.7% (at 550 nm). Flexible organic light-emitting diode, with a maximum 15000 cd m−2 luminance was successfully fabricated using such graphene and AgNWs composite transparent electrodes.

We have developed the transparent conductive electrode hybrid-gel films based on PEDOT:PSS and thin silver nanowires with diameters of 20 nm. These hybrid-gel films exhibited excellent opto-electrical performance and good mechanical flexibility.


In this study, we analyze the optical and electrical properties of silver nanowires/indium tin oxide transparent conductive electrode (TCE). Silver nanowire was synthesized by polyol method. ITO was deposited by direct-current sputtering. The diameter and length of the synthesized silver nanowire are in the range of 40-70 nm and 5-30 μm, respectively. The silver nanowire TCEs have a rather high resistance (~ 210 Ω /). After a layer of indium tin oxide sputtered on silver nanowire TCE, the resistance dropped sharply (~ 30.1 Ω/◻) corresponding to 84.1% transmittance at 550 nm. The figure of merit of this TCE is 68.3. This result shows that the fabricated silver naowire/indium tin oxide TCEs have great potential in application as window electrodes for solar cells and LED devices.
