透明导电电极是薄膜太阳能电池、发光二极管和许多显示技术的重要组成部分。掺杂金属氧化物是常用的材料，但对于方阻较低的薄膜，其光学透明性受到限制。此外，当它们沉积在柔性基板上时容易破裂，成本高昂，需要高温步骤才能获得最佳性能。我们展示了溶液处理的透明电极，它由金属纳米线的随机网状物组成，在相同的方块电阻下表现出与金属氧化物薄膜相同或更好的光学透明度。沉积在这些电极上的有机太阳能电池的性能与基于传统金属氧化物透明电极的器件相当。
Transparent conductive electrodes are important components of thin-film solar cells, light-emitting diodes, and many display technologies. Doped metal oxides are commonly used, but their optical transparency is limited for films with a low sheet resistance. Furthermore, they are prone to cracking when deposited on flexible substrates, are costly, and require a high-temperature step for the best performance. We demonstrate solution-processed transparent electrodes consisting of random meshes of metal nanowires that exhibit an optical transparency equivalent to or better than that of metal-oxide thin films for the same sheet resistance. Organic solar cells deposited on these electrodes show a performance equivalent to that of devices based on a conventional metal-oxide transparent electrode.
