TLDR
The overall properties of transparent Ag NW electrodes meet the requirements of transparent electrodes for many applications and could be an immediate ITO replacement for flexible electronics and solar cells.Abstract:
We report a comprehensive study of transparent and conductive silver nanowire (Ag NW) electrodes,includingascalablefabricationprocess,morphologies,andoptical,mechanicaladhesion,andflexibility properties, and various routes to improve the performance. We utilized a synthesis specifically designed for long andthinwiresforimprovedperformanceintermsofsheetresistanceandopticaltransmittance.Twenty/sqand 80% specular transmittance, and 8 ohms/sq and 80% diffusive transmittance in the visible range are achieved, whichfallinthesamerangeasthebestindiumtinoxide(ITO)samplesonplasticsubstratesforflexibleelectronics andsolarcells.TheAgNWelectrodesshowopticaltransparenciessuperiortoITOfornear-infraredwavelengths(2- foldhighertransmission).Owingtolightscatteringeffects,theAgNWnetworkhasthelargestdifferencebetween diffusive transmittance and specular transmittance when compared with ITO and carbon nanotube electrodes, a propertywhichcouldgreatlyenhancesolarcellperformance.AmechanicalstudyshowsthatAgNWelectrodeson flexiblesubstratesshowexcellentrobustnesswhensubjectedtobending.Wealsostudytheelectricalconductance ofAgnanowiresandtheirjunctionsandreportafacileelectrochemicalmethodforaAucoatingtoreducethewire- to-wire junction resistance for better overallfilm conductance.

Highly conductive silver nanowire transparent electrode by selective welding for organic light emitting diode
TL;DR: In this paper, a highly smooth, conductive and air-stable flexible transparent silver nanowire (AgNW) composite film is developed by solution process without high temperature treatment, and the sheet resistance of the AgNW/polyvinyl butyral (PVB) film decreases significantly after the film is immersed into the silverammonia and glucose mixed solution for only a few seconds.

TL;DR: It is demonstrated that the averaged resistivity of ITO nanowires can be decreased down to 2.1 × 10(-4) Ω cm, which is the lowest compared with values previously reported, via intentionally increasing the tin concentration within the Nanowires.

Robust and smooth UV-curable layer overcoated AgNW flexible transparent conductor for EMI shielding and film heater
TL;DR: In this paper, an overcoated silver nanowire flexible transparent electrodes (AgNW FTEs) with polymeric resins as an overlay layer were fabricated via successive Mayer rod method followed by UV light curing process, and the mechanical and chemical stabilities, electromagnetic interference shielding effectiveness (EMI SE) and film-heating property of the resultant over-coated AgNWFTEs were investigated.

Novel Patterning Method for Silver Nanowire Electrodes for Thermal-Evaporated Organic Light Emitting Diodes.
TL;DR: By controlling the surface wetting properties of a polydimethylsiloxane (PDMS) release template, a multilayer patterning and transferring process can be realized, resulting in a fine-patterned, smooth, and uniform AgNWs mesh/poly(3,4-ethylenedioxythiophene) polystyrenesulfonate ( PEDOT PSS) composite electrode.

The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.

TL;DR: The direct synthesis of large-scale graphene films using chemical vapour deposition on thin nickel layers is reported, and two different methods of patterning the films and transferring them to arbitrary substrates are presented, implying that the quality of graphene grown by chemical vapours is as high as mechanically cleaved graphene.
