On the long road towards low-cost flexible hybrid electronics, integration and printable solar energy harvesting solutions, there is an urgent need for high-performance transparent conductive electrodes produced using manufacturing-ready techniques and equipment. In recent years, randomly-distributed metallic nanowire-based transparent mesh electrodes have proven highly-promising as they offer a superb compromise between high performances and low fabrication costs. Unfortunately, these high figure-of-merit transparent mesh electrodes usually rely heavily on extensive post-deposition processing. While conventional thermal annealing yields good performances, it is especially ill-suited for deposition on low-temperature substrates or for high-throughput manufacturing solutions. Similarly, laser-induced annealing severely limits the processing time for electrodes covering large surfaces. In this paper, we report the fabrication of ultra high-performance silver nanowires-based transparent conductive electrodes fabricated using optimized manufacturing-ready ultrafast photonic curing solutions. Using conventional indium tin oxide (ITO) as our benchmark for transparent electrodes, we demonstrate a 2.6-2.7 [Formula: see text] performance gain using two different figure-of-merit indicators. Based on these results, we believe this research provides an ideal manufacturing-ready approach for the large-scale and low-cost fabrication of ultra high-performance transparent electrodes for flexible hybrid electronics and solar-energy harvesting applications.
在通往低成本柔性混合电子、集成和可印刷太阳能收集解决方案的漫长道路上，迫切需要使用具备量产能力的技术和设备来制造高性能透明导电电极。近年来，基于随机分布金属纳米线的透明网格电极已被证明极具潜力，因为它们在高性能和低制造成本之间实现了极佳的平衡。不幸的是，这些高优值的透明网格电极通常严重依赖大量的沉积后处理。虽然传统的热退火能产生良好的性能，但它特别不适用于在低温基板上沉积或用于高通量制造解决方案。同样，激光诱导退火严重限制了覆盖大面积电极的处理时间。在本文中，我们报告了使用优化的具备量产能力的超快光子固化解决方案制造的基于超高性能银纳米线的透明导电电极。以传统的氧化铟锡（ITO）作为我们透明电极的基准，我们使用两种不同的优值指标展示了2.6 - 2.7[公式：见正文]的性能提升。基于这些结果，我们相信这项研究为大规模、低成本制造用于柔性混合电子和太阳能收集应用的超高性能透明电极提供了一种理想的具备量产能力的方法。
