6 FAQs about [Photovoltaic cell separator]

How to separate a PV module from a solar cell?

The separated PV modules are filtered and sieved to obtain a mixture of glass and backsheet strips as well as a mixture of (solar cell + EVA) and backsheet. The glass and backsheet strips can be separated using hot air. Furthermore, an appropriate density reagent can be used to separate (solar cell + EVA) and backsheet.

How are solar cells separated?

Glass, solar cells, and ribbons are completely separated, as shown in Fig. 3. Pyrolysis has been proven to be an effective method to remove EVA encapsulants from the module laminates, therefore separating solar cells and module glass.

How to separate a solar cell from a backsheet?

The glass and backsheet strips can be separated using hot air. Furthermore, an appropriate density reagent can be used to separate (solar cell + EVA) and backsheet. Finally, pyrolysis is used to remove the residual EVA from the (solar cell + EVA) to obtain the solar cell.

Can a silicon-based PV module be separated using an electrostatic separator?

In this study, waste of silicon-based PV modules are separated using an electrostatic separator after mechanical milling. An empirical study is used to verify if the separation works and to select and fix several parameters.

How does electrostatic separation affect waste silicon photovoltaics?
