Flexible conductive electrodes are essential components for organic optoelectronic devices (OODs). One of the main challenges in the development of flexible OODs is to achieve an optimal combination of photoelectrical properties, enhanced flexibility and stability in transparent conductive electrodes (TCEs). In this work, high-performance flexible nonfullerene organic solar cells (OSCs) and polymer light-emitting diodes (PLEDs) based on TCEs of silver nanowires (AgNWs) encapsulated with an ultra-thin atomic layer deposited aluminum oxide (Al₂O₃) have been demonstrated. The hybrid AgNWs/Al₂O₃ composite electrodes with enhanced thermal, ambient and mechanical stabilities enable an efficient flexible transparent electrode with high transmittance and conductivity, which can synergistically optimize the device performance of nonfullerene OSCs and PLEDs. The maximum power conversion efficiency value of 7.03%, as well as a current efficiency of 7.26 cd A⁻¹ for flexible OSCs and PLEDs are achieved, respectively. Notably, excellent flexibility, long-term atmospheric and thermal stabilities have been systematically investigated and demonstrated. These results provide a new design platform for the fabrication of high-performance, flexible transparent electrodes, which can be further explored in a wide range of organic optoelectronics field.

柔性导电电极是有机光电器件（OOD）的基本组件。柔性OOD开发中的主要挑战之一是在透明导电电极（TCE）中实现光电性能，增强的柔韧性和稳定性的最佳组合。在这项工作中，基于银纳米线（AgNW）的传统文化表现形式的高性能柔性非富勒烯有机太阳能电池（OSC）和聚合物发光二极管（PLED）封装有超薄原子层沉积的氧化铝（Al ₂ O ₃）已经证明。混合AgNWs / Al ₂ O ₃具有增强的热，环境和机械稳定性的复合电极可实现具有高透射率和电导率的高效柔性透明电极，从而可协同优化非富勒烯OSC和PLED的器件性能。对于柔性OSC和PLED，分别实现了7.03％的最大功率转换效率值和7.26 cd A ^-1的电流效率。值得注意的是，系统地研究和证明了优异的柔韧性，长期的大气和热稳定性。这些结果为高性能，柔性透明电极的制造提供了一个新的设计平台，可以在有机光电领域广泛地进行探索。
