METHOD FOR RECYCLING SILICON FROM WASTE SOLAR MODULE

摘要

PURPOSE: A method for collecting silicon from a waste solar cell module is provided to improve the workability of a silicon collecting operation by establishing the optimal collecting condition. CONSTITUTION: A method for collecting silicon from a waste solar cell module includes the following: a waste solar cell module is immersed in a selected organic solvent; reinforced glass separated from a cell is primarily collected from the waste solar cell module; swallowed ethylene vinyl acetate is pyrolyzed from the cell and is removed; the cell is collected; a mixed acid solvent is prepared to remove an anti-reflective coat film and electrode materials from the collected cell; and a surfactant for increasing the collecting rate of silicon is added into the mixed acid solvent.
