Does salt etching reduce the environmental impact of solar cells?
The LCA analysis shows that the salt-etching process has a smaller environmental footprint in terms of carbon emissions, secondary waste production and energy consumption. Thus, this clean recycling method solves the upcoming material crisis and helps us to underpin the sustainable development of solar cells.
Is c-Si reclaimed from end-of-life Solar Cell photovoltaic?

Can solar panels be recycled?
Nature Sustainability 7, 920–930 () Cite this article The production and use of silicon (Si) solar panels is soaring during the transition to a carbon-neutral energy system. To mitigate their environmental footprints, there is an urgent need to develop an efficient recycling method to handle end-of-life Si solar panels.
Will C-Si solar panels be a waste?
As the lifetime of the c-Si solar panel is around 30 years, cumulative PV wastes will reach 80 Mt by 25. End-of-life (EoL) PVs, far from being wastes, are valuable urban minerals that can be used to extract materials to remake PVs and thereby close the material cycle 26.
How are EOL Si PV panels recycled?
EoL Si PV panels are recycled; this includes the recycling of Al frames and glass by induction melting; the separation of Ag and Si through salt etching; and the recovery of Cu, Pb and Sn from solders using a combined oxidation, alkaline leaching and electrochemical deposition method (Fig. 1).
