Lamination of solar panels keeps the solar cells protected by vacuum sealing and fusing the solar cell, the glass sheet, and the back sheet. While these seals are typically extremely secure, if the lamination process is not done correctly, delamination–the separation of the bond between these components–can occur.
The proposed method can prevent the depletion of polymer materials by allowing the recovery of 3.9 % of the solar module as a back-sheet polymer. With PV panel waste predicted to reach 60–70 million tons by 2050, this implies that at least 2.34–2.73 million tons of back sheet material could be recovered and reused.
