Highly stable and flexible silver nanowire–graphene hybrid transparent conducting electrodes for emerging optoelectronic devices

Abstract

A new AgNW–graphene hybrid transparent conducting electrode (TCE) was prepared by dry-transferring a chemical vapor deposition (CVD)-grown monolayer graphene onto a pristine AgNW TCE. The AgNW–graphene hybrid TCE exhibited excellent optical and electrical properties as well as mechanical flexibility. The AgNW–graphene hybrid TCE showed highly enhanced thermal oxidation and chemical stabilities because of the superior gas-barrier property of the graphene protection layer. Furthermore, the organic solar cells with the AgNW–graphene hybrid TCE showed excellent photovoltaic performance as well as superior long-term stability under ambient conditions.
