Planar silver nanowire, carbon nanotube and PEDOT:PSS nanocomposite transparent electrodes

Highly conductive, transparent and flexible planar electrodes were fabricated using interwoven silver nanowires and single-walled carbon nanotubes (AgNW:SWCNT) in a PEDOT:PSS matrix via an epoxy transfer method from a silicon template. The planar electrodes achieved a sheet resistance of 6.6 +/- 0.0 Omega/square and an average transmission of 86% between 400 and 800 nm. A high figure of merit of 367 Omega(-1) is reported for the electrodes, which is much higher than that measured for indium tin oxide and reported for other AgNW composites. The AgNW: SWCNT: PEDOT: PSS electrode was used to fabricate low temperature (annealing free) devices demonstrating their potential to function with a range of organic semiconducting polymer: fullerene bulk heterojunction blend systems
