Abstract

Renewable energy is changing the way we look at energy resources because its environment friendly and available in abundance while its counterpart, fossil fuels are limited and not environment friendly. We have proposed a graphene-based O-shaped metamaterial design for observing absorption behavior for different solar absorber regions. The O-shaped metamaterial design is also compared with simple square shape design for showing the betterment of design results using metamaterial inclusion. The design results are also investigated for variation in different parameters. The parameter variation is used for getting the best-observed design with substrate thickness, width, length and metasurface thickness of 2500 nm, 6000 nm, 6000 nm and 1000 nm respectively. The results are also analyzed for electric field intensity. The best observed O-shape metamaterial design is giving absorption in the range of UV, visible and infrared regions with average absorption of 86% ,93% and 80% respectively. The broadband response of this renewable solar absorber can be applicable for solar heating and photovoltaic applications.
