Backing foils and encapsulation material - Protection for solar cells

ISOVOLTAIC is a technology supplier of photovoltaics and has more than 25 years of experience in the production of high-quality composite protection films for solar cells with a production capacity of approx. 10 GWp per year.
The tried and tested ICOSOLAR® backing films from ISOVOLTAIC ensure that sunlight can be efficiently converted into electrical energy over a long period of time. On the one hand, they permanently protect the solar cells from mechanical, chemical and weathering influences and, on the other hand, the environment in front of the active elements – in the form of electrical insulation.

With ICOSOLAR® Encapsulant, ISOVOLTAIC also offers total solutions for the embedding of solar cells, which in combination with the back-up films as ICOSOLAR® plus or ICOSOLAR® complete revolutionize the market. ICOSOLAR® Encapsulant stands for excellent adhesion to solar glass as well as solar cell and back foil.
ICOSOLAR® products are tested in strict and comprehensive material tests. They are UL recognized, TÜV type tested and / or JET component registered. The benchmark for ICOSOLAR® is higher than the required standard standards. In addition to good long-term behavior, ICOSOLAR® is also characterized by its ease of use in module production and installation.
