Not all POE encapsulants protect TOPCon solar cells from corrosion

Not all POE encapsulants protect TOPCon solar cells from corrosion

UNSW researchers found that some POE encapsulants can trigger severe corrosion in TOPCon solar modules, causing up to 55% power loss under damp-heat conditions. Their study highlights that module reliability depends on the exact encapsulant formulation, not just the polymer type…
