Scientists and researchers in South Korea have developed a new and less-toxic method of recycling solar panels.
The research team from Korea Electronics Technology Institute and the Korea Interfacial Science and Engineering Institute have developed a method of removing silicon wafers from worn out solar panels. Instead of using toxic chemicals like hydrofluoric acid, the team heats the panels at high temperatures (480°C) in a furnace. This process melts the glue that holds the wafers. The undamaged silicon wafer is recycled by various processes before it is ready for use with new solar cells. Other researchers consider this to be an innovative, cheaper and cleaner way of recycling solar panels.
