New method recovers 97% of silver from old solar panels
Original: 97% of silver recovered from dead solar cells using acid-free molten salt bath
Researchers have developed an acid-free molten salt bath technique that recovers 97% of the silver from dead solar cells, offering a cleaner way to recycle end-of-life photovoltaic panels. The method avoids corrosive acids, and interest is focused on its potential to cut recycling costs and recover valuable materials as the first big wave of solar panels reaches retirement.
Why now: Solar panel waste is growing rapidly, so a cleaner, high-yield silver recovery process is timely news for the recycling and energy sectors.
