Abstract
As a new investigation for renewable energy generation, the recent three-layer solar structure is composited with three effective material usages of Al (resonator), InSb (substrate), and Ag (based). The overall wavelength of overall 2800 nm with the bandwidth order from 0.2 to 3.0 μm is 91.68%, the extracted percentage is 97.07% at 800 nm (1.41-2.21) µm, and the output is 95.02% with the 1420 nm wavelength by the bandwidth separation of 1.09 and 2.51 μm respectively. With the graphene accumulation in this absorber, the radiated output can be determined in the first visible area, the second ultraviolet region, and the near-infrared spectra respectively. The multi-step exploration of the absorbed rate in design performance, the selected materials and parameter assignments, and the analyzed parametric numbers for each layer will be included in the proposed presentation. The demonstrated solar structure can be performed at the low-temperate rate of less than 100 °C for heating processes of water or space, between 100 and 250 °C for industrial processes, and above 250 °C to release the steam for running turbines in the electricity generation.
