6 FAQs about [Principle of photovoltaic panel silicon wafer removal equipment]

How to reclaim silicon (Si) wafer from end-of-life photovoltaic module?

A sustainable method for reclaiming silicon (Si) wafer from an end-of-life photovoltaic module is examined in this paper. A thermal process was employed to remove ethylene vinyl acetate and the back-sheet. We found that a ramp-up rate of 15 °C/min and an annealing temperature of 480 °C enabled recovery of the undamaged wafer from the module.

Why is silicon wafer recovery important for solar panels?

Ultimately, silicon wafer recovery is indispensable for the solar panel industry, facilitating efficient resource usage, extending product lifespan, and improving overall performance.

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.).

How to recycle Si wafer from solar PV module?

Processes to recycle Si wafer from solar PV module The junction box, aluminium frame and cables have been separated mechanically which are attached with the help of adhesive glue (Silica gel). Mechanical separation is the only method to remove them without damage.

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.

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.
