Challenges of vacuum roll-to-roll processing of organic solar cells and encapsulation processes

摘要

Heliatek uses an efficient roll-to-roll process in vacuum and inert atmosphere to manufacture highly flexible solar films. Our product Heliafilm(R) consists of a multi-layer system of organic small-molecular materials which is deposited in vacuum onto a pre-structured PET/TCO substrate and successively encapsulated into a barrier film system to protect it from water and oxygen.
