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
