BR-PV-FMC NH₃ / Moist Carbon Dioxide / Sulphur Dioxide
Flowing Mixed Gas Corrosion Test Chamber

Implementation of standards: UL 1703-2008, IEC 60068-2-60:1995
IEC 62716 "Ammonia corrosion testing of photovoltaic (PV) modules":2010 (draft-B)
(IEC 62716 reference ISO 12944, ISO 3231, ISO 6988 and DIN 50018 relevant provisions.)

Mothed: Dominant potential failure mechanisms in the reaction of ammonia with PV modules are identified by applying different ammonia concentrations to PV modules and its components (encapsulation materials, front glass...) and evaluating the damage mechanisms by various analytical methods. The permeation of ammonia through encapsulant and back skin materials (EVA and Tedlar/ PET/ Tedlar) are evaluated quantitatively.
