Abstract
A cost-effective approach of building graphene-based photodetectors with Ag nanowires (AgNWs) as the contact electrode on the glass substrate via solution process has been developed. The transmittance of the graphene/glass and the AgNWs/graphene/glass at a wavelength of 550 nm is 74% and 67%, respectively. To further improve the performance of the graphene photodetector, Ag nanoparticles are applied on the graphene to obtain the enhanced photocurrent and the improved ON/OFF ratio of 505 by the surface plasmon resonance effect. This semi-transparent graphene photodetector shows the superior optical and electrical performance and it paves the way to the future development of graphene-based devices by costly and high-throughput techniques.
