Abstract
Silver nanowires (Ag NWs) network is considered a promising alternative to replace indium tin oxide (ITO) as transparent conductive electrode (TCE). However, there are several intrinsic shortcomings such as rough surface topography, poor ambient and thermal stability still restrict their practical application. Here, we demonstrated a low temperature solution-processed composite TCE comprising of Ag NWs and ZnO nanoparticles (NPs) could resolve above issues. The highest temperature in whole process is no more than 100â¯Â°C. By optimizing the density of Ag NWs together with the thickness of ZnO NPs layer, the composite TCE showed excellent flexibility, ambient and thermal stability (â¼300â¯Â°C) as well as high electrical conductivity (â¼20â¯Î©/sq) and good optical transparency (â¼87% at 550â¯nm). In addition, the ZnO NPs capping layer reduced the surface roughness of Ag NWs network by more than half of its initial value. All the demonstrated properties show the Ag NWs/ZnO composite TCE would be an ideal choice in a variety of flexible optoelectronic devices.
