Can crystalline-silicon photovoltaic panels be recycled?

The recyclable fractions can be used for the production of secondary raw materials, thereby allowing relevant benefits in terms of substitution of primary raw materials. This present report focuses on the recycling of crystalline-silicon photovoltaic panels which still dominate the present market.

What materials can be recycled for photovoltaic panels?

In the case of aluminium, copper and silver, the expected recovered/recycled materials are assumed to substitute primary materials. The recovered solar glass is assumed to be down-cycled into glass for packaging; electronic-grade silicon metal used in photovoltaic panels is assumed to be recovered as MG silicon metal with lower purity.

How much silicon is in a PV panel?

Fthenakis has published more on the subject than anyone, to my knowledge. His LCA lists a whole bunch of factors, but it's roughly 1.5kg of silicon in the PV itself. But a module also has 16.1kg of tempered low-iron glass for a 210 Wp panel (p32). Glass is 60-80% silica, and silica is about half and half silicon and oxygen by weight.

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.

What is a crystalline silicon solar panel?

A typical crystalline silicon solar panel comprises glass (70%), aluminum (18%), adhesive sealant (5%), silicon (3.5%), plastic (1.5%), and other materials (2%), as outlined in Table 2.
