    The module is then crushed in a mill and the different fractions are separated – glass, plastics and metals. [82] It is possible to recover more than 80% of the incoming weight. [ 83 ] This process can be performed by flat glass recyclers, since the shape and composition of a PV module is similar to flat glass used in the building and ...

    A fraction of the blue light undergoes the Stokes shift, which transforms it from shorter wavelengths to longer. Depending on the original LED's color, various color phosphors are used. Using several phosphor layers of distinct colors broadens the emitted spectrum, effectively raising the color rendering index (CRI).
