PV module recycling tech based on heavy liquid separation, metal chloride etching

AI Summary

Researchers in China have developed a novel three-step recycling process for crystalline silicon photovoltaic modules that recovers valuable materials like high-purity silicon and metals while reusing reagents. The method significantly reduces carbon emissions by over 80% compared to traditional recycling approaches.

Researchers in China have developed a three-step recycling process for end-of-life crystalline silicon PV modules that recovers high-purity silicon, copper, silver compounds, and other valuable materials while enabling reagent reuse. Life cycle and techno-economic analyses showed the process can cut carbon emissions by 80.42% compared with conventional methods and generate positive returns from solar-cell and solder-strip treatment stages.
