Graphene-based metasurface solar absorber design with absorption prediction using machine learning
Scientific Reports, 2022 Solar absorber is required to absorb most of the energy of the solar spectral irradiance. We propose a graphene-based solar absorber design with two different metasurfaces to improve this absorption and increase the efficiency of the solar absorber.
