Particularly, the focus lies on the advantageous recovery of high-value silicon over intact silicon wafers. Through investigation, this research demonstrates the feasibility and cost-effectiveness of silicon wafer recovery from damaged silicon solar panels.
A sustainable method for reclaiming silicon (Si) wafer from an end-of-life photovoltaic module is examined in this paper. A thermal process was employed to remove ethylene vinyl acetate and the back-sheet. We found that a ramp-up rate of 15 °C/min and an annealing temperature of 480 °C enabled recovery of the undamaged wafer from the module.
In this review article, the complete recycling process is systematically summarized into two main sections: disassembly and delamination treatment for silicon-based PV panels, involving physical, thermal, and chemical treatment, and the retrieval of valuable metals (silicon, silver, copper, tin, etc.).
