go PV 5. Lamination Process & PV Module Materials Flexible membrane Upper chamber (P) EPFL • Heating plate (T) Modulé stack Lamination <<recipe»: combination of steps in the process. • • Specific to a given encapsulant. Critical in ensuring the modules' long-term performance. Lamination parameters: • • • Temperature (T) Pressure (P) Time (t) • Poor lamination process → occurrence of failure modes in the field (e.g. delamination). *In a good laminator the temperature uniformity of the heating plate is well controlled below ≤ 2°C.
