What is the difference between EVA film and backsheet?

What you want to ask is, what is the difference between EVA film and back film? The uses are different.

In the photovoltaic industrial chain, EVA films and backsheets are mainly used in the packaging of photovoltaic modules. EVA films can be used in photovoltaic components such as crystalline silicon cells and thin-film battery modules. TPE: thermoplastic elastomer. It is mainly used in the production of backsheets in solar cells. EPE: Expandable polyethylene.

EVA film can replace PET to produce the back sheet of solar cells. The process of packaging photovoltaic modules is irreversible. The lifespan of the battery module should be more than 25 years. of the battery module begins to turn yellow, crack, the battery is prone to breakdown and disposal.

How longs lasts EVA photovoltaic film?

The raw materials for the production of EVA film are mainly rubber particles. This material does not produce harmful gases, but chemicals are involved in the production. The substance is glue, which is a toxic gas. It is recommended to wear a gas mask. If the company does not provide you with one, you should choose another company because your health comes first and your work second.

20 years. The Aikang Solar R&D Center is expected to develop an EVA film with an average lifespan of 30 years. The average life of domestic EVA films is 20 years, and there are problems such as moisture resistance and heat resistance, UV aging and light transmission. . Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into energy.electrical energy.
