  • Method of recycling solar cell module
    Patent number: 10388812
    Abstract: A method of recycling a solar cell module includes an enclosing layer that encloses a solar cell therein, a light-receiving surface layer laminated on one surface of the enclosing layer, and a back sheet laminated on the other surface of the enclosing layer, the method including: a first removing step of mechanically removing the back sheet; a second removing step of mechanically removing from a side on which the back sheet is removed the entire solar cell and the enclosing layer to such a depth that a part of the enclosing layer having a predetermined thickness remains on the light-receiving surface layer, after the first removing step; and a third removing step of removing the part of the enclosing layer remaining on the light-receiving surface layer by immersion in a solution that causes swelling of the enclosing layer, after the second removing step, thereby improving an overall efficiency.
