6 FAQs about [PV panel EVA film content]

Is Eva a transparent solar module?

EVA is known for its excellent transparency. This means that the optical transmission is acceptable and doesn't block too much of the sunshine trying to reach the solar cells. Nowadays, several manufacturers in Asia use a transparent backing, which has transparency between the cells as a result. This type of module is known as semi-transparent.

Can X-ray photoelectron spectroscopy detect EVA encapsulants in PV modules?

While Fourier-Transform Infrared spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) are well established to analyse EVA encapsulants in PV modules, X-ray Photoelectron Spectroscopy (XPS) is seldomly used.

Are PV panels used in experiment a defective product?

Actually, the PV panels used in experiment are defective products during the production process, but the structure of module is complete. These unqualified modules are stacked and some have been for several years. Those PV modules are ideal raw materials for research.

Does Eva film Bond to solar glass?

Under the right circumstances, EVA film will have excellent adhesive bonding to solar glass (NOT standard glass, solar glass has a rough surface). Also EVA bonds very well to the backsheet. EVA is known for its excellent transparency.

Can XPS be used to study EVA copolymers for photovoltaics?

The results clearly confirm the high potential of XPS for more complex studies of EVA copolymers for photovoltaics, such as interactions of EVA and other, esp. inorganic materials, in PV module laminates along with interfacial degradation phenomena. As depicted in Fig. 9, XPS is far more surface sensitive than IR-ATR and DSC.

Is microwave-enhanced Eva film swelling and separation effective for PV panels recycling?

In this paper, a new method of microwave-enhanced EVA film swelling and separation for PV panels recycling was innovatively proposed. The results showed that the separation speed of different layers in microwave can be significantly accelerated. Different swelling agents were compared and trichloroethylene was proved to be the most effective.
