PV module recycling should prioritize high-purity silicon recovery

Recovering silicon of the quality required for reuse in panels is at the heart of mitigating device carbon footprints. R&D efforts should be ramped up now, says an international research group, so the technology is in place when huge volumes of modules begin to need replacing.An international research team led by the U.S. Department of Energy's National Renewable Energy Laboratory has emphasized the importance of the R&D effort aimed at recovering high-purity silicon from end-of-life solar modules. The authors of the paper Research and development priorities for silicon photovoltaic module recycling ...
