6 FAQs about [Photovoltaic panel EVA glass separation]

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.

Why is it important to separate different layers of PV panels?

It is very important to realize the rapid and efficient separation between the different layers of the PV panels. After the separation of different layers, valuable materials such as silver wires, silver paste electrodes, and Cu/Sn ribbons be exposed which is necessary for the extraction the valuable materials.

How to determine the degree of separation of PV panels?

In order to evaluate the degree of separation of PV panels, the separation rate of PV panels was introduced in this paper and it was determined by Eq. (1): (1) Separation rate ( %) = ( 1 − M b M a) × 100 where Mb is the mass of unseparated PV panels and Ma is the total mass of the PV panels placed in the reactor.

Can Egda be used to separate glass-Eva in photovoltaic modules?

Non-toxic reagent EGDA was used to separate the glass-EVA in photovoltaic modules for the first time. The glass in 20 mm × 20 mm photovoltaic pieces can be separated adequately in 3 h. EGDA can be recycled by filtration to be reused. Solar cells can keep their initial size due to the moderate swelling ability of EGDA.

Does temperature affect the separation efficiency of PV panels?

It has implied that the temperature may has a greater impact on the separation between different layers, as it affects the TEC of the material. Thus, the effect of temperature in the microwave field on the separation efficiency of PV panels was studied.

How to detach glass and Eva backsheets from solar cells?

Scientists in China developed a novel swelling process to detach glass and EVA backsheets from solar modules at the end of their lifecycle. The technique utilizes an ester of a dicarboxylic acid known as dibasic ester. It reportedly prevents excessive cracking of solar cells.
