  • Solar-thermal conversion member, solar-thermal conversion device, and solar thermal power generation device comprising a ?-FeSi2 phase material
    Patent number: 9546801
    Abstract: A solar-thermal conversion member includes a ?-FeSi2 phase material. The solar-thermal conversion member exhibits a high absorptance for visible light at wavelengths of several hundred nm and a low absorptance for infrared light at wavelengths of several thousand nm and, as a consequence, efficiently absorbs visible light at wavelengths of several hundred nm and converts the same into heat and exhibits little thermal radiation due to thermal emission at temperatures of several hundred ° C. The solar-thermal conversion member may therefore efficiently absorb sunlight, provide heat, and prevent thermal radiation due to thermal emission.
