1.Its mental layer at bottom is typically made of aluminum. 2.Absorption layer and antireflective layer are compound of Nitrogen and aluminium ion.Membranous layer is about 0.3 micron.
3.In order to reduce energy loss through heat emission, the most efficient absorbers have a selective surface coating, which is rinsed by the water moved ion so that the selective coating can be adhere to the tubes firmly .
