Silver nanowires (Ag NWs) as transparent conducting electrodes are widely used in many applications such as organic light-emitting diodes (OLEDs), polymer light-emitting diodes, touch screens, solar cells, and transparent heaters. In this work, using a large-scale synthesis, the synthesized Ag NWs had a high aspect ratio of 2820. The Ag NWs could be applied as a top transparent electrode in a device by simple drop-casting without any post-processing steps. The fabricated device comprised 4,4'-bis(carbazol-9-yl)biphenyl/MoO organic/inorganic layers which are parts of the inverted structure OLEDs or solar cells. The photodiode characteristics at the UV range were observed in the device. The ability of Ag NWs to replace opaque metals as top electrodes in a device has been demonstrated.
银纳米线（Ag NWs）作为透明导电电极被广泛应用于许多领域，如有机发光二极管（OLED）、聚合物发光二极管、触摸屏、太阳能电池和透明加热器。在这项工作中，通过大规模合成，合成的Ag NWs具有2820的高纵横比。Ag NWs可以通过简单的滴铸法应用于器件中作为顶部透明电极，无需任何后处理步骤。所制备的器件包含4,4'-双（咔唑-9-基）联苯/MoO有机/无机层，它们是倒置结构OLED或太阳能电池的组成部分。在该器件中观察到了紫外范围内的光电二极管特性。已经证明了Ag NWs在器件中作为顶部电极替代不透明金属的能力。
