Because of the flourishing development of optoelectronic and electronic devices, the transparent electrodes (TEs) market is thriving. Today the dominant material used in TEs is still tin-doped indium oxide (ITO). However, the scarcity and high cost of indium element leads to the tight supply of ITO. Furthermore, the ceramic nature of ITO, which is brittle, is unfavorable for its integration with the flexible devices. The emerging Ag nanowires (NWs) network TEs can be considered as the most promising candidate for replacing commercial ITO. Ag NW TEs can provide the high electrical conductivity and high optical transparency like ITO. It also overcomes the shortcomings of ITO TEs such as non-toxicity and brittleness. Because of these advantages in Ag NW TEs especially flexibility, it will help organic light-emitting diodes (OLEDs) get better optoelectronic and mechanical performance. In this research, we focus on the development of the Ag NW network anodes, which will be applied in OLED cells, on glass or flexible substrates. The optical and electrical properties of Ag nanowire network film will be studied and demonstrated.
