Photovoltaic adhesive board auxiliary materials

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].

What is PVB encapsulation?

PVB is a thermoplastic polymer which has been used since the early 80s as a PV module encapsulant. It represents the second most processed encapsulation material, with similar material costs to EVA.

Can Pu be used as an encapsulate material for PV modules?

However, very few works have been made to explore the application of PU as an encapsulate material for PV modules.

Can UV curable acrylate adhesive be used as encapsulate for PV module?

In a study, a UV curable acrylate adhesive with phenyl ether functionality has been employed as encapsulate for the PV module . Phenyl ether groups enhanced the barrier performance of acrylate encapsulate by providing hydrophobicity to the acrylate matrix and also promoted their adhesive nature with untreated PET substrate.

What materials are used for PV module frontsheets?

The most common material used for PV module frontsheets is low iron (<120 ppm Fe) float glass. Functional coatings are added to the surfaces of the glass to increase light adsorption (anti-reflective coatings) and/or to reduce the accumulation of dirt and debris on the module in the field (anti-soiling coatings).

Are antireflective and anti-soiling coatings suitable for PV modules?

The durability of the candidate materials still has to be tested within a test module und combined stresses in order to check its suitability. Antireflective (AR) coatings have been commonly used in PV modules since ~2005, and anti-soiling (AS) coatings have been explored for use in PV since ~2015.
