Why is ultra-fine silicon cutting powder important in photovoltaic industry?

The rapid development photovoltaic industry has generated a huge amount of waste ultra-fine silicon cutting powder. The management and value-added recovery of silicon cutting waste is highly important for both environmental remediation and economic efficiency.

Will PV waste panels reduce the need for raw silicon extraction?

On the other hand, silicon is included in the 2020 EU list of critical raw materials (Raw Materials Information System (europa.eu)); thus, the recovered silicon from PV waste panels would decrease the need for raw silicon extraction and improve the circularity of the European economy.

Why is the photovoltaic industry considering recycling PV modules?

The photovoltaic industry is considering options of recycling PV modules to recover metals such as Si, Ag, Cu, Al, and others used in the manufacturing of the PV cells. This is to retain its “green” image and to comply with current legislations in several countries.

How metallurgy is used to make solar panels?

Once the frame component is separated from the PV module, other materials such as iron, silicon, and nickel are extracted through metallurgy [Dias et al. (2018); Granata et al. (2014) recycled silicon solar cells (poly and amorphous) and CdTe PV panels through a two-blade rotor crushing and hammer crushing process.
