Silver nanowires (AgNWs) and graphene can be used in a high-performance electrode to obtain a transparency over 95% due to their exceptional properties as transparent-electrode materials. However, even though the electrical conductivity of the AgNW is excellent, it cannot obtain a further performance improvement such as a higher transparency without changed parameters. Here, we are proposing a technique to improve the performance of highly transparent electrodes by introducing an AgNW-grid patterning that can enhance the contact density between nanowires (NWs) for the enhancement of their electrical properties. The electrical performance of the patterned AgNW-grid depends on the channel width and the fill factor. The 95 %-transparent-patterned-AgNW grid reduced the sheet resistance by 9.22% compared with the unpatterned-AgNW network under an identical transparency condition, and further, the effect is more dominant under much higher transparency conditions. The contribution of graphene is important for the transparent electrode since it can completely cover the electrode surface while improving electrical properties of the patterned-AgNW grid by 100.59% with a 98.06% transparency, which is higher than that of the unpatterned-AgNW network under an identical transparency condition.

使用图案化银纳米线和石墨烯层状材料实现超透明电极

银纳米线 (AgNWs) 和石墨烯可用于高性能电极，由于它们作为透明电极材料的特殊性能，可以获得超过 95% 的透明度。然而，即使 AgNW 的导电性非常好，它也不能在不改变参数的情况下获得进一步的性能改进，例如更高的透明度。在这里，我们提出了一种通过引入 AgNW 网格图案来提高高度透明电极性能的技术，该图案可以增强纳米线 (NW) 之间的接触密度，从而增强其电性能。图案化 AgNW 网格的电气性能取决于通道宽度和填充因子。95% 透明图案的 AgNW 网格将薄层电阻降低了 9。在相同的透明度条件下，与未图案化的 AgNW 网络相比，增加了 22%，而且，在更高的透明度条件下，效果更显着。石墨烯的贡献对于透明电极很重要，因为它可以完全覆盖电极表面，同时将图案化的 AgNW 网格的电性能提高 100.59%，透明度为 98.06%，高于未图案化的 AgNW 网络在相同的透明度条件。
