作为柔性透明导电电极,铜纳米线具有达到甚至超过氧化铟锡性能的潜力。然而,为了大规模生产,它们需要以高速,低成本的方式制造,而不会降低柔性基板。其中一个主要的瓶颈是在形成透明电极后去除纳米线表面的有机残留物的后处理,这是获得高光电性能所必需的。在这里,我们建议紫外线照射和随后的醋酸浴作为一个简单的,可扩展的,快速的后处理。经过2分钟的紫外线处理,然后是10分钟的酸浴,测得Rs为42 Ω sq−1,t550 nm为87%。此外,铜纳米线电极在750-2500 nm范围内保持高透明度,这使其成为红外太阳能电池等应用的良好候选者。
Copper nanowires have the potential to reach and even exceed the indium tin oxide performances as flexible transparent conductive electrodes. However, for a large-scale production, they need to be fabricated in a high-speed, low-cost way, without degrading the flexible substrate. One of the major bottlenecks resides in the post-treatment used to remove organic residues from the surface of the nanowires after forming the transparent electrode, which is necessary to obtain high optoelectronic performances. Here, we propose an ultra-violet irradiation and a subsequent acetic acid bath as an easy, scalable, fast post-treatment. After only 2 min of ultra-violet treatment, followed by 10 min of acid bath, an Rs of 42 Ω sq−1 and a T 550 nm of 87% were measured. Besides, copper nanowire electrodes maintained their high transparency in the range 750–2500 nm, which makes them good candidates for applications such as infrared solar cells.
