Abstract

In this study, the optimized process conditions of a scraper, which is a device used to separate glass from a solar module, are presented for structural analysis, and the actual module separation is confirmed experimentally. Because a strong load is concentrated on the scraper blade, it is necessary to derive the optimal process conditions for effective module separation while minimizing the damage to the blade. Structural analysis was performed using a finite element model (FEM) to evaluate the stress, reaction force, and strain applied to the blade recycling the waste solar modules. The optimal process conditions were determined from the structural analysis according to the angle and surface temperature of the blade. Module separation experiments were conducted by applying the elicited process conditions, and the results showed smooth module separation that enabled the recovery of high-purity tempered glass.
