Agfa’s ‘ARZONA BS+’ is a high-performance backsheet for crystalline silicon PV modules that builds on Agfa’s 100+ years of experience in chemical-coating formulation, polyester extrusion and multi-layer coating know-how. ARZONA BS+ is a clear film based on polyethylene terephtalate (PET) with high-quality coated layers on both sides to provide extra protection against humidity and UV.

Problem: The backsheet material is required to withstand long-term environmental impact, providing strong adhesion and protection to the module’s solar cells in order to meet a module lifetime expectation of over 25 years.

Solution: ARZONA BS+ uses a unique coated FPU-layer structure, i.e. fluoropolymer/polyester/UV-protection, to provide long-lifetime power output efficiency, durability and safety. On the cell side, the PET core layer is coated with Agfa’s U-layer, providing strong adhesion to the encapsulant and protecting the core against UV radiation. On the air side, a fluoropolymer-coated layer offers protection against humidity and UV.

Applications: Backsheets for crystalline silicon PV modules.

Platform: ARZONA BS+ is a backsheet with a PET core, characterized by excellent mechanical properties, and is claimed to have one of the lowest shrinkage levels available on the market.

Availability: Currently available.
