Recycled silicon used in 19.7% efficient PERC solar cells
Led by German research institute Fraunhofer ISE, the consortium has built the solar cells with 100% crystalline silicon recycled from end-of-life photovoltaic panels. The silicon is recycled through a technique conceived by German specialist Reiling GmbH & Co. KG and the Fraunhofer Center for Silicon Photovoltaics CSP.
