文摘

The nonmetal filler (TiN) is included into the SiO2 host to achieve the sunlight absorption. The substrate effect on the thermal stability is investigated. A stable solar absorptance of 94% with a super long-term thermal stability up to 700 °C is achieved in the spectrally-selective solar absorber deposited on lanthanum aluminate substrate.
