摘要：A full-spectrum solar energy allocation design based on nanopattern-free multilayered coatings (MLCs) is proposed to boost photovoltaic-thermoelectric (PV-TE) energy conversion efficiency. Above- and below-bandgap photons are sent to gallium arsenide (GaAs) cells and absorptive layers lying between GaAs cells and TE devices, respectively. A low-averaged reflectance of ∼7.9%for full-spectrum solar energy under one-Sun AM0 conditions is achieved due to multiple interferences and graded refraction index. A high-averaged absorptance of ∼93.62%and ∼91.17%for below- and above-bandgap photons are obtained with the assistance of impedance matching enabled by MLCs. Performances are shown to be also insensitive to incident angles, polarization states, and each layer's thickness. We pave the way to design efficient space-based PV-TE energy conversion systems. © 2019 Society of Photo-Optical Instrumentation Engineers (SPIE).
