6 FAQs about [Chemical purification process of photovoltaic panels]

What are the different process approaches to PV panel recycling?

Three different process approaches to PV panel recycling are distinguished and detailed in the remainder of the section: physical treatment and EVA dissolution with organic solvents, thermal treatment, and chemical processes. Processes relying on the combined application of these process approaches are separately discussed. 7.1. Physical treatment

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.).

What are reactants used for in the chemical treatment of photovoltaic panels?

Many reactants are used in the chemical treatment of photovoltaic panels, especially when the objective is the recovery of metals or the reuse of the wafers.

How to deal with solar PV waste material?

Therefore, the methods of dealing with solar PV waste material, principally by recycling need to be established by 2040. By recycling solar PV panels EOL and reusing them to make new solar panels, the actual number of waste (i.e., not recycled panels) could be considerably reduced.

How is photovoltaic waste treated in India?

India recycling regulations: As of now, India lacks specific rules and regulations dedicated to the management of photovoltaic (PV) panel waste, and it is currently treated under general waste regulations (Preet et al., 2023).

How to purify a broken PV cell?

The solid PV silicon was washed with deionized water several times and then dried under vacuum at 100 °C overnight, which is referred as impurity-free PV recycled silicon. Approximately 32 g of dried silicon was collected after purification (≈80% recovery).The process can purify large quantity of broken PV cells.
