Which material is most preferred for reflector of a parabolic trough collector? Back-silvered thick-glass reflectors are the most widely used type of reflector for parabolic-trough concentrators. This type of reflector is similar to conventional mirrors apart from the curvature and the type of glass used. What are solar reflectors made of? An optical solar reflector (OSR) 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...
