The impending wave of decommissioning of photovoltaic (PV) modules, installed in the early 2000s and reaching gigawatt scale by 2030, poses a significant environmental and social challenge.End-of-life silicon PV modules, abundant in high-purity trace metals, offer a significant potential for recycling.We have developed an innovative and sustainable chemical process that combines low-concentration alkaline solutions with iron chloride for the efficient recovery of aluminium and metallic silver from waste solar cells.This process is characterized by a minimal environmental impact, reducing the life cycle assessment impact by half compared to conventional methods.
