S. Korea KIER Touts Solar Panel Recycling Technique (Int'l.)
Korea Institute of Energy Research
Date: 2021-08-20
In Seoul, the state-run Korea Institute of Energy Research (KIER) reports it has developed a non-destructive technique to recycle discarded solar panels to create high-performance solar cells. The new technique can recycle both undamaged and damaged panels to achieve up to 100 pct retrieval rate of glass component and roughly 80 pct of other materials can be retrieved and recycled into high-performance solar cells.

KIER Researchers were able to refine silicon collected from 72 discarded commercial panels into six-inch single crystal ingots and wafers. Recycled materials were used in the production of solar cells with a generation efficiency of about 20.52 pct. Normal solar cells have an energy efficiency of about 15 pct.

South Korea's total solar energy generation capacity stood at 3.65 GW in November 2020. (Source: Korea Institute of Energy Research, PR, Aug., 2021) Contact: Korea Institute of Energy Research, www.kier.re.kr/eng
