Near-infrared transparent electrodes constitute an essential component of light-emitting and photovoltaic devices widely employed in short- and long-range communication, light detection and ranging, biodiagnostics, security, virtual and augmented reality, night vision, gas sensing, and solar cells. However, the efficiency of all these devices and related applications suffers from significantly reduced transmittance of the indium tin oxide electrode compared to the visible wavelength range. Here, we explore the potential of randomly and uniformly arranged silver, gold, and aluminum nanopore and nanowire films for the near-infrared optoelectronics. We show that these metallic nanopatterned layers, except for randomly arranged nanoporous configurations, exhibit considerably higher performance than the commonly used indium tin oxide. Furthermore, silver layers possess higher transmittance and lower haze than gold and aluminum ones, while the nanowire configuration overperforms the nanoporous one. The obtained results offer a means for deeper analysis of metallic nanopatterned transparent electrodes for many near-infrared optoelectronic applications.

用于近红外光谱的纳米图案金属透明电极

近红外透明电极构成了广泛用于短距离和远程通信，光检测和测距，生物诊断，安全性，虚拟和增强现实，夜视，气体传感和太阳能电池中的发光和光伏设备的重要组成部分。然而，与可见光波长范围相比，铟锡氧化物电极的透射率显着降低，所有这些装置和相关应用的效率都受到影响。在这里，我们探索了随机，均匀排列的银，金和铝纳米孔和纳米线薄膜对于近红外光电子学的潜力。我们表明，这些金属纳米图案层，除随机排列的纳米多孔结构外，比通常使用的铟锡氧化物具有更高的性能。此外，与金和铝相比，银层具有更高的透射率和更低的雾度，而纳米线的配置优于纳米多孔的配置。获得的结果提供了一种用于许多近红外光电应用的金属纳米图案透明电极的更深层分析的手段。
