Solar Spectral Beam Splitting Performance and Regulation Study on Aluminum-Based Nanofluid
This study aims to match the splitting characteristics of the nanofluid with the photovoltaic response and thus improve the efficiency of the concentrating photovoltaic thermal (CPV/T) system. In this paper, the optical properties of aluminum (Al) nanoparticles are investigated by using the finite-difference time-domain method, and it is found that changing the particle size can achieve the modulation of the extinction properties of nanoparticles, including the extinction intensity and resonance peak range. To optimize the optical properties of Al nanoparticles and to solve the problem of their easy oxidation, the extinction properties of Al@Ag nanoparticles with different shell thicknesses were designed and analyzed. It was found that the extinction ability of the particles with core-shell structure was enhanced. When Al and Al@Ag nanoparticles are dispersed into water to form nanofluid, the transmittance is effectively reduced in the short wavelength band compared to pure water. The core-shell structure can reduce the transmittance by up to 13% and 10% in the 350–650nm band compared with the pure Al particles of 50nm and 60nm particle size, and has almost no effect on the transmittance in the photovoltaic window (640–1080nm). Therefore, the efficiency of the CPV/T system can be effectively improved by the regulation of Al nanoparticles.
