According to their experiment results, the complete dis- solution of EVA on the sample panel was attained at a temperature of 70 °C and an irradiation power of 900 W using 3MO-DCB within
30 min, and the PV cell was recovered without any cracks. 5 N Plus which is a Canadian metal refiner tested on an irradiation process which aims at destruction of EVA by laser through the glass [47]. However, the process is slow and requires very expensive equip- ment, and therefore still far from industrial application. Yu and Yang [48] suggested that delamination technologies commonly used in the existing recycling processes of Si modules have the disadvantage of degradation and breakage of cells. Therefore, they proposed a hotwire cutting-based delamination process for c-Si based modules. As the cover glass and the substrate can be removed after the cutting, giving more room for EVA swelling during following thermal or chemical treatments, wafer cracks can hopefully be reduced.
