Hybrid silver nanowire and graphene based solution-processed transparent electrode for organic optoelectronics
The research on transparent conductive electrodes (TCEs) is in rapid ascent in order to respond to the requests of novel optoelectronic devices. The synergic coupling of silver nanowires (AgNWs) and high-quality solution-processable exfoliated graphene (EG) enables an efficient transparent conductor with low surface roughness of 4.6 nm, low sheet resistance of 13.7 Ω sq-1 at high transmittance and superior mechanical and chemical stabilities. The developed AgNWs-EG films are versatile for a wide variety of optoelectronics. As an example, when used as bottom electrode in organic solar cell (OSC) and polymer light-emitting diode (PLED), the devices exhibit a power conversion efficiency of 6.6% and an external quantum efficiency of 4.4% respectively, comparable to their commercial ITO-counterparts.
