Graphene-silver nanoparticle composites for effective solar absorption are prepared by coupling surface plasmon and optical absorption of individual phases as low cost materials. Optoelectronic and morphological properties are studied with varying synthetic conditions to optimize their photothermal response. Plasmonic silver nanoparticles encapsulated in graphene layers act as localized solar heating elements of its surrounding medium, because of which a significant heating is observed. The tested composites are quite stable under prolong exposure to solar radiation and hence may find potential applications in various fields.
