Can solar panels be sustainable?
In addition, Cu, Pb, Sn and Al in Si solar panels are also recovered through a combined oxidation, alkaline leaching and electrodeposition approach. Overall, this study presents a viable approach for sustainable management of end-of-life Si solar panels, paving the way to a circular economy.
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.
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).
How can Si PVs make the solar industry sustainable?
No harmful acids and wastes are involved in this approach, which contributes to the closure of the material supply chain of Si PVs, thereby making the solar industry sustainable.
How are Si solar cells treated with molten NaOH–KOH?
Four types of Si solar cells (for example, Al-BSF, PERC-I, PERC-II, TOP-Con) were treated with molten NaOH–KOH using the SDH approach (Fig. 2a–d). For Al-BSF solar cells, the SiNx layer was completely removed, and Ag wires were liberated from Si wafers after salt etching at 200 °C for 90 s (Fig. 2a(i)–(xii)).
