New tech to demetallize, recrystallize solar cells from end-of-life PV modules

An international team of researchers has proposed a series of processes to recover silicon and other metals from recycled solar cells. Their goal is to reuse the recovered silicon in the PV supply chain. A European group of scientists has investigated the technical feasibility of physical recovery of the metal contacts from solar cells extracted from end-of-life solar panels and the qualification of the recovered silicon for its reuse in the PV supply chain. "This reality urgently calls for the design and adoption of affordable, effective, and massive strategies of recycling and re-utilization ...
