An optical solar reflector (OSR) is a component of a vehicle or machine designed to fly in outer space. The reflector consists of a top layer made out of quartz, over a reflecting layer made of metal. OSRs are used for radiators on spacecraft. The quartz outer layer lets the solar light through which reflects on the metal layer. This results in a low absorption coefficient. The quartz layer is a good IR emitter. The result of these properties is … WebKai Sun et al. VO2 Thermochromic Metamaterial-Based Smart Optical Solar Reflector, ACS Photonics (2024). DOI: 10.1021/acsphotonics.8b00119 Kai Sun et al.
