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 , , .

Is Eva a good encapsulant for PV panels?

As a further side note, the use of EVA as encapsulant for PV panels came from the U.S. JPL Low-Cost Silicon Array Program in the late 1970s. However, JPL did warn in their development that EVA could have such problems under those harsh conditions.

Can Eva/go nanocomposite films be used as encapsulant for PV modules?

Since the EVA encapsulant is susceptible to attack by molecular oxygen in auto-oxidation type reactions. This research indicated good perspectives for the use of EVA/GO nanocomposite films as encapsulant for PV modules.

What grade of Eva is used in PV modules?

The grade of EVA primarily used in PV modules is Elvax 150; this corresponds to 33 wt.% vinyl acetate content. Acetic acid is removed in the first decomposition stage of EVA as shown from the TGA results, which represents 23 wt.% of the vinyl acetate monomer.

Does Eva encapsulation affect PV module performance?

The EVA function and properties correlated to its deterioration factors as temperature, moisture, and ultraviolet radiation (UV) were discussed in this work. The main objective of this study is to review the literature on EVA encapsulation and its degradation, which promotes the loss in performance of the PV module.

Why is stabilization mechanism of Eva important for photovoltaic module encapsulation?

It is of fundamental importance to promote stabilization mechanisms of EVA as photovoltaic module encapsulant, as its degradation leads to the formation of products which adversely affect the operation and integrity of the photovoltaic module . 5.3.2. Techniques for photodegradation evaluation
