Contrary to conventional technologies, like shreddering, we do not break the glass. Using technologies from the field of optical nanotechnology it has been possible to fully open the sandwich structure, without damaging the glass. Both, water and light are the key components. The methods in combination allow recycling for almost all PV module types with the respective preservation of the glasses and this process actually opens the way for the photovoltaic industry to become part of the circular economy. So the technology is very environmentally friendly. The process has the right to separate all processed materials and to reuse them. Our hydrometallurgical extraction operates at room temperature and the used alkane sulfonic acid is readily biodegradable (OECD 301 A). We describe the procedure, the schematic structure and the working principle of a novel universal recycling system for End-of-Life photovoltaic modules and for production scrap also.
