It aims to effectively enhance the solar absorptance and solar-thermal efficiency of CSP and TPV, while allowing the structure to operate at high temperatures without degradation. The optical performance of the optimal absorber in the wavelength range of 280–4000 nm was obtained using the FDTD method.
To ensure efficient solar-thermal conversion of the structure in high-temperature operating environments, the geometric structure of the one-dimensional multilayer metamaterial absorber is optimized based on the AM1.5 radiation and high-temperature operating condition under 1000 suns and a temperature of 1273 K.
Analysis of the spectral selective mechanism shows that the high solar absorptance of the optimal absorber is attributed to the impedance matching with free space, which is a result of the coupling effect between SPPs and MPs. Kunpeng Yuan: Writing – original draft, Methodology, Formal analysis.
Taking into account the infrared radiation loss, the solar-thermal efficiency of the absorber is found to be 91.2% under 1000 suns at 1273 K, and the total emittance is 0.1504 at the corresponding temperature. The absorber shows high insensitivity to both incident polarization angles and wide-angle incidence.
