Flexible and Transparent Metallic Grid Electrodes Prepared by Evaporative Assembly

Abstract: We propose a novel approach to fabricating flexible transparent metallic grid electrodes via evaporative deposition involving flow-coating. A transparent flexible metal grid electrode was fabricated through four essential steps including: (i) polymer line pattern formation on the thermally evaporated metal layer onto a plastic substrate; (ii) rotation of the stage by 90° and the formation of the second polymer line pattern; (iii) etching of the unprotected metal region; and (iv) removal of the residual polymer… Show more

“…The angled (45°) polyethylene terephthalate (PET) blade was coupled to a vertical translation stage, and a linear translation stage was coupled to a piezo nanopositioner. 33 The substrate temperature was heated mildly to 60°C by a hot plate positioned under the linear translation stage to accelerate solvent evaporation. The PTTDPP-DT-DTT solutions dissolved in four different solvents (CF, Tol, CB, or DCB) were introduced between the PET blade and the ODTS-treated SiO 2 /Si substrate.…”

“…While grids have been realized with nanoscale lines in several studies, the fabrication relied on subtractive multistep patterning methods such as imprinting, [ 14,15,20 ] lithography, [ 15 ] or evaporative self-assembly. [ 16 ] For microscale line widths, although not completely additive, an elegant method using selective laser sintering of a silver or nickel nanoparticle fi lm has been presented by Hong et al [ 17 ] and Lee et al, [ 18 ] respectively. A direct ink writing approach of concentrated silver inks has been shown by Ahn et al, demonstrating linewidths around 5 µm.…”

“…Recently, carbon nanotubes (CNT) [11,12], graphenes [3,13], metal grid or metal nanowires [14][15][16], conducting polymers [17,18] with attractive mechanical, electrical and optical properties have been extensively studied. Among them, CNT and, more recently, graphene have attracted significant attention and have shown potential use in organic light emitting diodes and solar cells [19,20].…”
