Single-reagent tech to reuse silicon from end-of-life PV panels achieves recovery rate of 98.9%. Scientists in Singapore developed a single-reagent approach to recover silicon in recycled PV panels that reportedly offers high recovery rates compared to double-reagent methods. The recycled silicon was then effectively reused in anodes intended for applications in lithium-ion batteries.
A group of scientists led by Nanyang Technological University (NTU) in Singapore has developed a process to recycle silicon from end-of-life PV panels that reportedly offers a recovery rate of up to 98.9%.
“The NTU approach demonstrated a higher recovery rate and purity than present silicon recovery technologies,” the research’s lead author, Sim Ying, told pv magazine. “We used the recovered silicon in a lithium-ion battery anode and tested it for efficiency. Results showed that it performed similarly to new, commercially bought silicon.”
