Technical requirements for separation of photovoltaic silicon wafers
Metal electrodes, anti-reflection coatings, emitter layers, and p-n junctions must be eliminated from the solar cells in order to recover the Si wafers. There is difficulty in separating glass from PV wafer due to the adhesive material between silicon s silver from crystalline panels and 96. 10% silver from CIS PV. . ABSTRACT: Thermal Laser Separation (TLS) is a damage free and kerfless dicing technology for brittle materials like silicon (Si) wafers and solar cells. 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. .
