A typical thin and fully flexible hybrid electrode was developed by integrating the encapsulation of silver nanowires (AgNWs) network between a monolayer graphene and polymer film as a sandwich structure. Compared with the reported flexible electrodes based on PET or PEN substrate, this unique electrode exhibits the superior optoelectronic characteristics (sheet resistance of 8.06 Ω/□ at 88.3% light transmittance). Meanwhile, the specific up-to-bottom fabrication process could achieve the superflat surface (RMS = 2.58 nm), superthin thickness (∼8 μm thickness), high mechanical robustness, and lightweight. In addition, the strong corrosion resistance and stability for the hybrid electrode were proved. With these advantages, we employ this electrode to fabricate the simple flexible organic light-emitting device (OLED) and perovskite solar cell device (PSC), which exhibit the considerable performance (best PCE of OLED = 2.11 cd/A; best PCE of PSC = 10.419%). All the characteristics of the unique hybrid electrode demonstrate its potential as a high-performance transparent electrode candidate for flexible optoelectronics.
一种典型的薄而全柔性混合电极是通过将银纳米线（AgNWs）网络封装在单层石墨烯和聚合物薄膜之间作为夹层结构来制备的。与基于 PET 或 PEN 基底的报道的柔性电极相比，这种独特的电极具有优异的光电特性（透光率为 88.3%时的方阻为 8.06 Ω/□）。同时，特定的自下而上的制造工艺可以实现超平整表面（RMS = 2.58nm）、超薄厚度（约 8μm 厚度）、高机械鲁棒性和轻量化。此外，该混合电极具有较强的耐腐蚀性和稳定性。由于这些优点，我们使用该电极制备了简单的柔性有机发光器件（OLED）和钙钛矿太阳能电池器件（PSC），其性能相当可观（OLED 的最佳 PCE = 2.11cd/A；PSC 的最佳 PCE = 10.419%）。这种独特混合电极的所有特性都表明其作为高性能透明电极用于柔性光电的潜力。
