Abstract: PURPOSE: A method for collecting silicon from solar cell module waste is provided to collect pure silicon and recycle the collected silicon as a silicon wafer by collecting cells from the solar cell module waste and eliminating a non-reflective coating layer and electrode materials from the cells. CONSTITUTION: Solar cell module waste is immersed in an organic solvent in order to collect cells(11) based on the swelling phenomenon of ethylene vinyl acetate(EVA)(12). Trichloroethylene, o-dichlorobenzene, or toluene is used as the organic solvent. Reinforced glass(14), separated from the cells based on the swelling phenomenon of the EVA, is collected. Cells attached to the EVA are passed through a furnace of 500-700 degrees Celsius under an inert atmosphere condition in order to pyrolyze the EVA. The cells are collected. A mixed acid solvent is obtained by mixing distilled water, nitric acid, fluoric acid, sulfuric acid, and acetic acid. A mixed solvent is obtained by additionally mixing surfactant to the mixed acid solvent. The collected cells are immersed in the mixed solvent to dissolve a non-reflective coating layer and electrode materials. Pure silicon is collected.

Abstract: PURPOSE: A method for recycling silicon from a used solar cell is provided to immerse a used solar cell in a mixed acid solvent for proper time to eliminate a non-reflection coat film and an electrode material, thereby recycling the used solar cell as a silicon wafer. CONSTITUTION: The composition of a mixed acid solvent and the immersion time of a used solar battery cell(11) are determined to obtain an optimum silicon collecting rate from the used solar battery cell. The mixed acid solvent melts a non-reflection coat film and an electrode material in the used solar battery cell according to the composition of the mixed acid solvent. The composition of the used solar battery cell is cut by a fixed weight. The cut solar battery cell is immersed in the mixed acid solvent during the determined immersion time. When the non-reflection coat film and the electrode material of the used solar battery cell are melted in the mixed acid solvent, pure silicon is obtained.

Abstract: PURPOSE: A silicon collecting method from a used solar cell module is provided to increase productivity and to reduce costs required for producing solar cells by collecting and recycling expensive silicon. CONSTITUTION: A used solar cell module is immersed in organic solvent in order to collect solar cells based on the swelling phenomenon caused by ethylene vinyl acetate(EVA). Tempered glass separated from the solar cells is pre-collected. The solar cells attached to the swollen EVA undergo a pyrolyzing operation in the furnace at 500 to 700 degrees Celsius under an inert atmosphere, and the EVA is eliminated. Mixed acid solvent is prepared by mixing distilled water, nitric acid, fluoric acid, sulfuric acid, and acetic acid in order to eliminate an anti-reflective coating film and electrode materials from the cells. 5 to 25% of surfactant based on the total volume of the mixed acid solvent is added to the mixed acid solvent to obtain mixed solvent. The collected cells are immersed in the mixed solvent for 15 to 25 minutes to collect pure silicon.
