foil widths of 35 cm wide. Roll-to-roll production scale machines of
the key processes for foils in excess of 1.2 meter width have been
designed and are in the stage of ramping up. Highly flexible and
light weight PV products with efficiencies ranging from 7 up to 11%
are produced. The highly flexible and light weight product has been
successfully tested at TüV and thus passes the lifetime and safety
tests that are required for the high quality PV modules in the market.
