Transparent electrodes (TEs) based on indium tin oxide (ITO) have been widely used as an essential element of various organic photovoltaic (OPV) devices. However, it possesses several drawbacks such as high cost, brittleness, and high processing temperature. Therefore, cheap, flexible, and solution-processed TEs have been required for emerging OPV devices. Recently, silver nanowires (AgNWs) TE showed the superior optical and electrical performance comparable to ITO. However, they still have issues on a long-term stability and electrical connection, which make them difficult for practical use. In this work, we fabricated a AgNW-Graphene hybrid TE to overcome its issues due to the graphene layer acted as both efficient electron transport pathway and excellent gas-barrier property. Furthermore, OPV devices with the AgNW-Graphene hybrid TE showed excellent photovoltaic performance as well as superior long-term stability under ambient conditions. |
