Abstract

A wideband absorber-based solar energy harvester operating in infrared (IR), visible, and ultraviolet (UV) regions is investigated in this paper. The resonating structure comprises a rectangular notch-loaded trapezoidal-shaped metallic section arranged symmetrically along four corners. Its unit cell dimension is 90×90×10 nm³ and achieves more than 90% absorption (A) for the frequency range of 189.31 to 4308.958 THz. It is polarization-dependent but has A≥90% throughout the operating frequency band for Transverse Magnetic (TM) as well as Transverse Electric (TE) modes. This absorber has A≥90% for incident angle (θ)≤50^o and A≥80% for θ≤60^o in both of the TE and the TM modes. The designed absorber achieves 97.30% solar absorption efficiency (

η_{A}

) along with the thermal emission efficiency (

η_{E}

) of 81.45%, 92.55%, and 96.44% at 1000K, 2000K, and 3000K, respectively. A high Photo-Thermal Conversion Efficiency (PTCE) of 97.26% is observed at 100 K temperature with a solar concentration (C) of 100.

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
