How to use flexible photovoltaic panel encapsulation film

Which material is used to encapsulate PV modules?

Ethylene vinyl acetate EVA, a copolymer of ethylene and vinyl acetate is the predominating material of choice for manufacturing the encapsulate film since the early eighties, and nearly 80% of PV modules are encapsulated with EVA film [4, 13, 29].

Does encapsulate film improve cooling rate of PV module?

Encapsulate film with improved thermal conductivity enhances the cooling rate of the PV module. Encapsulate film exhibited good resistance for water vapor transmittance. Optically transparent encapsulate film exhibited good resistance for weather degradation.

How to encapsulate solar cells?

In the solar industry, the most common encapsulation is with cross-linkable ethylene vinyl acetate (EVA). With the help of a lamination machine, the cells are laminated between films of EVA in a vacuum, which is under compression. This procedure is conducted under temperatures of up to 150 °C.

What is PV encapsulate?

Generally, the encapsulate is a polymeric film which plays a critical role in avoiding environmental degradation or improving the stability of PV cells through the formation of a cross-linking network structure during the lamination of the PV module.

What encapsulant is used in solar panels?

In addition, a polyisobutylene edge sealant (Lange et al., 2011) and an aluminum frame is applied around the module (Cattaneo et al., 2014). Currently the most common polymeric encapsulant material in commercial silicon solar modules is ethylene–vinyl acetate (EVA) (Kempe, 2011, Peike et al., 2013).

Why is encapsulation of PV modules important?

Encapsulation of PV modules is one among the multiple ways to mitigate these stability issues and it plays an important role in the enhancement of the device lifetime by providing a barrier structure to restrict the penetration of oxygen and moisture.
