Optical path
Transmission and clarity help light reach the cell surface efficiently.
APPLICATION GUIDE / 01Solar encapsulation
Solar encapsulation
grade-screening guide
In a photovoltaic module, encapsulation material sits between the glass, solar cells and backsheet. The formulation must support a stable lamination process while balancing optical, adhesive and protective performance.
01 / ROLE OF EVA
EVA resins used in film systems for optical transmission, adhesion and module protection.
EVA is widely used as an encapsulation layer around solar cells, helping protect the electrical core while transmitting light into the module.
Optical transmissionLamination responseLong-term protection
Lamination behavior
Controlled flow and cure response support repeatable module processing.
Interlayer protection
The encapsulant helps isolate and protect sensitive components inside the module.
02 / INFORMATION FOR GRADE SCREENING
What to include in an enquiry
A complete process description is more useful than a grade number alone.
Equipment and conditions
Conversion method, temperature profile, line speed, residence time and any known processing constraints.
Other materials in the system
Fillers, crosslinkers, tackifiers, waxes, additives, blend partners or layer construction.
Required test results
List target properties, test methods, acceptance limits and relevant service conditions.
Trial and supply information
Sample quantity, packaging preference, expected annual volume and required qualification timing.
