Nearly perfect metamaterial plasmonic absorbers for solar energy applications

In this study, two different approaches for the design of broadband polarization-independent wide-angle metamaterial plasmonic absorbers (MPA) are presented. The proposed MPAs are made of periodic arrays of Nickel (Ni) or Wolfram (W) cubes. The top surfaces of the cubes are texturized using silicon dioxide (SiO2). The proposed PMAs with two different optimized textures experience plasmonic resonance characteristics that enable near unity visible light absorption. The parametric studies carried on the proposed MPAs with the aid of 3D-FDTD method results in wide-angle near perfect absorption characteristic that is > 0.96 for all visible regimes. Additionally, the obtained results show almost perfect absorption of above 99% over the frequency ranges extending from ~ 458 to ~ 525 and ~ 489 to ~ 665 THz. Besides, numerical results demonstrate that the proposed PMAs also exhibit both polarization and angle independency for the whole visible regime. Further, the absorption characteristics of proposed MPAs near the infrared and ultraviolet regimes are investigated.
