▎ 摘　　要

Solar energy absorption for the whole spectral irradiance is important which includes UV, visible and infrared regions. We have proposed a new metasurface solar absorber design by optimizing the different metasurface designs to absorb most of the solar radiation. The design results are obtained for two metasurface designs namely plus-shape metamaterial design and I-shape metamaterial design. The absorption result comparison of these two designs clearly shows that the plus-shape metamaterial design is having more absorption for all three regions. The highest average absorption of 95% is observed for the visible region for plus-shape metamaterial design. The design results for different parameter variations such as thickness, width, length, etc. are observed and an optimized design is obtained. The design results for the angle of incidence are also observed which clearly shows that the design is having a wide angle of incidence. The graphene potential variation is not affecting the overall absorption of the design. The proposed solar absorber with its wide angle of incidence and high absorption in the solar spectrum can be used for solar thermal energy conversion applications.
