Which crystalline materials are used in solar panels?
Cadmium and Se are not considered critical (therefore not shown); however, they are also used in thin-film PV and battery applications (Simandl et al., 2021) Overall, crystalline Si, CdTe technology, and CIGS account for 92%, 5%, and 2% of the solar panel market, respectively.
Are PV materials a co-product of base or precious metal recovery?
In most cases, PV materials are co-products of base or precious metal recovery. However, under current market conditions, the recovery of these co-products is not economical for many operations. For example, during Cu production, slimes from copper anodes are an important potential source of critical materials (e.g., Se, Te, As, Sb, and Bi).
