The panels are heated to 300 °C with oxidant agents to decompose the plastic layer, and after cooling, the remaining metal components are recovered. The pyrolysis heating process effectively removes glass and EVA layers from silicon solar panels, recovering 90% of silicon wafers (Nieland et al., 2012).

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.
