About Can the photovoltaic panel silicon wafer still be used if it breaks
Upcycling aims to recover high-grade glass, silicon wafers and valuable metals including Ag, Cu and Al from EOL c-Si PV panels. After mechanical or manual removal of Al frames, junction boxes and cables, the economic cycle is facilitated by a two-step process: (1) module delamination and (2) recovery of silicon wafers and valuable metals.
