6 FAQs about [How to extract metal materials from photovoltaic panels]

What metals can be recovered from photovoltaic modules?

Recovering valuable metals such as Si, Ag, Cu, and Al has become a pressing issue as end-of-life photovoltaic modules need to be recycled in the near future to meet legislative requirements in most countries. Of major interest is the recovery and recycling of high-purity silicon (>99.9%) for the production of wafers and semiconductors.

How to recycle photovoltaic solar cells?

This study recycles photovoltaic solar cells by leaching and extraction. According to the analyst, Silicon cells content 90% of Si, 0.7% of Ag, and 9.3% of Al. Silicon cells were leached by 4M nitric acid at 80°C for 4 hours then 3M sodium hydroxide at 70°C for 3 hours, and the leaching efficiency were 99.7% of Ag, and 99.9% of Al, respectively.

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.

What materials can be recovered from EOL solar panels?

Byungjo Jung et al., reported the recovery of valuable materials (Si, Al, Ag, Cu, Sn) and hazardous metal (Pb) from the EoL solar panel. The solar panel was immersed in 5 M nitric acid and subjected to stirring @ 200 rpm. They successfully recovered Si followed by Cu, Ag, Al and Pb.

How to recover silver metal from solar panel waste?

The aim of this study was to develop a recycling process to recover silver metal from solar panel waste. Experimental procedure consisted of mechanical/physical separation, leaching of silver from silicon wafer and precipitation to retrieve silver chloride (AgCl) precipitate.

Can a PV panel reduce EPBT?

An estimate in Italy showed that the EPBT of a PV panel could be reduced by 1.7% when recovery and recycling are accounted into the manufacturing cycle . The reduction in EPBT brought by effective recovery and recycling of PV panels can be equalized to 1% increase in efficiency .
