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… https://www.pv-magazine.com/2026/01/16/not-all-poe-encapsulants-protect-topcon-solar-cells-from-corrosion/
