Market Trends, Materials & Manufacturing Processes

go PV 5. Lamination Process & PV Module Materials Encapsulant Ethylene Vinyl Acetate copolymer (EVA) has the best properties - cost ratio. [CHE_CH₂] [CH n H CH₂ C m EPFL Front Glass Encapsulant Stringed cells Encapsulant H₂C C Multiple additives are present in the commercial EVA rolls: ☐ Backsheet or Rear glass Curing agent → cross-linking reaction during lamination. UV absorbers. UV stabilizers/anti-oxidants = decompose curing agent residues; Adhesion promoters → increase adhesion between EVA and glass.
