Abstract

We have presented graphene-based metasurface tri-layer highly efficient broadband solar absorber. Below metasurface and above dielectric layer a monolayer graphene sheet is inserted to achieve maximum average absorption in visible terahertz (430 THz to 770 THz) spectrum. We demonstrated a broadband solar absorber with 85% absorptance in the visible terahertz band. The single C shaped unit cell of metasurface solar absorber made up of tungsten separated by the tungsten ground plane by a silicon dioxide dielectric layer. The proposed absorber also investigated to manipulated absorbtance of absorber by varying different parameters of structure. The graphene metasurface solar absorber has a potential application for the development of terahertz lasers and sensors.
