We report on highly transparent conductive hybrid thin-films based on copper (Cu)-mesh structures combined with conductive polymer films. The hybrid films show outstanding optical and electrical properties (transmittance of 81.7% at a wavelength of 550 nm, sheet resistance of 71.3 Ω/sq). The effective current collecting property of metal mesh structures as well as the excellent current spreading property of the conducting polymer enables the high performance of the hybrid transparent electrodes. Organic light-emitting diodes (OLEDs) employing the hybrid transparent electrodes result in 2.0-fold enhanced current and power efficiencies, compared to the control polymer electrode-based OLED without current collecting metal mesh structures. The results present that Cu-mesh structures combined with conductive polymer films show great promise for applications in low-cost, flexible indium tin oxide-free OLEDs.

我们报道了基于铜（Cu）-网状结构与导电聚合物薄膜相结合的高透明导电混合薄膜。杂化膜显示出出色的光学和电气特性（在550 nm波长下的透射率为81.7％，薄层电阻为71.3Ω/ sq）。金属网状结构的有效集流性能以及导电聚合物的优异电流扩散性能可实现混合透明电极的高性能。与没有集流金属网状结构的基于对照聚合物电极的OLED相比，采用混合透明电极的有机发光二极管（OLED）导致电流和功率效率提高了2.0倍。
