Transparent electrodes (TEs) are important parts for optoelectronic devices such as solar cells, organic light emitting diodes, liquid crystal display, and touch panels. Indium tin oxide (ITO) is the most widely used material for TE, but, it has some drawbacks: brittleness and scarcity of indium resources. In this regard, various types of research on alternatives, such as carbon nanotube, graphene, and metal nanowires, have been actively carried out. Especially, silver nanowire (AgNW) films have advantages of high optical transmittance and electrical conductivity. However, since AgNW is quite vulnerable to air and moisture, it can be oxidized and corroded easily. To overcome this limitation, we fabricate reduced graphene oxide (rGO)-AgNWs hybrid TEs on poly (ethylene terephthalate) (PET) for improving their electrical conductivities and long-term stability of neat AgNWs. The rGO-AgNWs hybrid TEs can be a promising candidate for ITO and further applied to organic solar cells. |
