Abstract

Copper nanowires (CuNWs) with ultrahigh aspect ratio are synthesized with a solution process and spray-coated onto select substrates to fabricate transparent conductive electrodes (TCEs). Different annealing methods are investigated and compared for effectiveness and convenience. The CuNWs are subsequently combined with the conductive polymer poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) or with reduced graphene oxide (rGO) platelets in order to reduce the surface roughness and improve the durability of the fabricated TCEs. Our best-performing PEDOT:PSS/CuNW films have optical transmittance T₅₅₀ = 84.2% (at λ = 550 nm) and sheet resistance R_s = 25 Ω/sq, while our best CuNW/rGO films have T₅₅₀ = 84% and R_s = 21.7 Ω/sq.
