Design and Investigation of Surface Plasmon Resonance Solar Absorber Based on Graphene for Renewable Energy Applications

With the wide use of solar energy systems nowadays, we are profiting from natural resources and reducing electric bills. To create the perfect broadband absorber, combining the selected material in each layer and the appropriate resonator design plays an important role. With the efficiency of solar energy, our living standards can develop with the home facilities in daily life. We invented the current Al-Al2O3-InAs three-layer absorber intended to be used for several thermal purposes from small facilities to large amounts of electrical power generation processes. The recent absorber output can relate the absorption percentages 97.21%, 95.2%, and 92.6% in 400 nm, 1340 nm, and 2700 nm wavelength rates. The recent three-layer absorber work can be applied to some thermal processes of heating and cooling systems in medical devices, buildings, imaging, industrial places, and diagnostic systems.
