After adding a hardener or crosslinking agent, a mechanically resistant adhesive layer is obtained.
  • a disadvantage of these adhesive systems is that the hardening process often releases aggressive substances, such as acids, which can destroy the photosensitive semiconductor layers, in particular thin-film modules.

This is easily possible for the person skilled in the art through orientation experiments.
