Time-domain modeling of silver nanowires-graphene transparent conducting electrodes

Abstract

Transparent conducting electrodes (TCE) consisting of silver nanowires (SNW) with a single-layer graphene (SLG) cover demonstrate higher optical transparency and lower sheet resistance than indium tin oxide (ITO) and are comparable to the best reported results in TCEs. SNW layer is simulated using the spectral averaging of the FDTD transmittance data from indiscriminately selected frames. Simulations are done for a number of frames until a convergent set of averaged spectra is obtained. SLG layer is simulated separately and contributes to the total transmittance as a multiplicative constant.
