Does PV module aging require optical coupling between Eva encapsulant and PV cells?

The main conclusions are: PV module aging demands on optical coupling between the EVA encapsulant and PV cells in which the polymer acts as protection against environmental stress.

Which material is used to encapsulate a photovoltaic module?

For about three decades, the material-of-choice used as the encapsulant is the ethylene vinyl acetate copolymer (EVA) and nearly 80% of photovoltaic (PV) modules were encapsulated by EVA materials , , .

How does UV aging affect PV module corrosion?

In the case of EVA, UV aging also leads to VA loss in the form of acetic acid, which determines the PV module corrosion. In order to study the effects of UV aging, all samples have been exposed to four UV doses 22, 74, 126 and 214 kWh/m 2, indicated respectively with 1, 2, 3, 4 UV, in a climatic chamber.

Which encapsulant is best for photovoltaic modules?

EVA is currently the most used encapsulant in the photovoltaic field; TPO and POE are new materials, alternative to EVA, which can allow to overcome some of the reliability problems of photovoltaic modules linked to the degradation of EVA properties.

How does UV aging affect PV encapsulant degradation?

The obtained results from the UV aging tests show that a PV encapsulant degradation also depends on its formulation, that is, the kind and amount of the used additives, as well as from the used main polymer base.

Can polymeric materials be used for photovoltaic modules encapsulation?

This work aims to investigate the change in chemical and physical properties of different polymeric materials, potentially usable for photovoltaic modules encapsulation, caused by UV aging. Three classes of polymeric materials have been examined: ethylene-vinyl-acetate (EVA), thermoplastic polyolefins (TPO) and polyolefin elastomers (POE).
