“…It is difficult to reduce the thickness to under 150 nm in the case of single ITO films because of the resulting, significant, decrease in electrical conductance [5]. However, a very thin metal film can be deposited between two ITO films to result in a higher conductivity than that of a single ITO layer of the same thickness [5] and to improve the mechanical properties due to the ductile metallic interlayer [6]. Such a multilayer system has been proved to be effective in achieving electrically conductive and optically transparent electrodes by optimizing the thickness of the ITO layer [7].…”

We investigated the electrical and optical properties of ITO/Ag-alloy/ITO films in a corrosive NaCl solution. The effects of bending fatigue combined with aggressive environments provided by the salt solution were also studied. It is shown that exposure to the salt solution can cause the ITO/Ag-alloy/ITO performance to degrade over time. In addition, greater changes in electrical resistance and lower values of optical transmittance were observed at higher concentrations of the salt solution. The combination of stress and corrosion by the aqueous NaCl solution was found to significantly reduce the conductivity of the ITO/Ag-alloy/ITO film. Furthermore, it is shown that the presence of structural defects in the deposited films can provide a driving force to form Ag agglomerations that, in turn, degrade the conductivity of the ITO/Ag-alloy/ITO film. This suggests that defects in the film should be minimized to avoid excessive corrosion.
