Photovoltaic Industrial PVB Film
For years now, PVB has been the preferred plastic for safety glazing. These properties, combined with proven high long-term stability in outdoor applications even in non-edge-protected glazing, assure module manufacturers of the long-term protection of solar cells sandwiched between PVB films.
For the crystalline solar cells most frequently produced and processed internationally, PVB films transparent are used, and exclusively in glass/glass PV modules. If a back sheet film is used as the barrier layer on the reverse, the use of suitable back sheet films (e.g. with an Al barrier layer) is recommended.
