6 FAQs about [Extracting precious metals from solar photovoltaic panels]

Can MFC technology improve metal recovery from chemical extract of PV panels?

This study investigates the MFC technology as an alternative method for valuable metal recovery from the chemical extract of PV panels. Moreover, metal recovery from the chemical extract is compared with the individual recoveries obtained using corresponding synthetic solutions.

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.

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.

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.

How are silicon PV modules recycled?

Recycling of silicon PV modules essentially involves three main stages : (i) manual/mechanical disassembly of decommissioned PV panels which yields the aluminum frame, junction boxes and copper cables; (ii) delamination via mechanical, chemical or thermal [3, 13] treatment for glass recovery and (iii) leaching/etching for metal extraction.

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.
