6 FAQs about [How to smelt metal from waste photovoltaic panels]

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 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.

Can crystalline silicon PV panels be recycled?

Although the amount of waste photovoltaic (PV) panels is expected to grow exponentially in the next decades, little research on the resource efficiency of their recycling has been conducted so far. The article analyses the performance of different processes for the recycling of crystalline silicon PV waste, in a life cycle perspective.

Why do we need to recycle end-of-life photovoltaic waste?

Due to the massive generation of photovoltaic waste (expected 34,600 T by 2030), stringent recycling effort to recover metal resources from end-of-life PVs is required for resource recovery, circular economy, and subsequent reduction in the environmental impact.
