6 FAQs about [The role of photovoltaic panels in extracting silicon wafers]

Are recycled silicon wafers suitable for solar cells?

The photovoltaic (PV) industry uses high-quality silicon wafers for the fabrication of solar cells. PV recycled silicon, however, is not suitable for any application without further purification, as it contains various impurities.

Can silicon wafers be recovered from damaged solar panels?

Through investigation, this research demonstrates the feasibility and cost-effectiveness of silicon wafer recovery from damaged silicon solar panels. As photovoltaic technology continues to advance rapidly, there is a pressing need for the recycling industry to establish adaptable recycling infrastructure to accommodate evolving industry needs.

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.

What is the recycling process for silicon-based PV panels?

In this review article, the complete recycling process is systematically summarized into two main sections: disassembly and delamination treatment for silicon-based PV panels, involving physical, thermal, and chemical treatment, and the retrieval of valuable metals (silicon, silver, copper, tin, etc.).

Can silicon PV wafers be separated from glass before pyrolysis?

Some researchers have introduced a delamination method before the pyrolysis treatment, wherein silicon PV wafers are physically separated from glass (Doni and Dughiero, 2012). There is difficulty in separating glass from PV wafers due to the adhesive material between silicon solar cells and glass.

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.
