Summary:To provide a recycling technique capable of recovering a material at low cost and high yield.SOLUTION: A recycling method is applied to a solar cell module 20 assembled with a cover glass 23, a cell layer 21B, and a sealant 24 bonding these. In the recycling method, an interface between the cover glass 23 and the sealant 24 is heated to a predetermined temperature range, a force is applied to the sealant 24 from a side face of the solar cell module 20 in a state that the interface maintains the predetermined temperature range, and the sealant 24 and the cell layer 21B are peeled off from the interface.SELECTED DRAWING: Figure 11 【課題】低コスト及び高収率で材料を回収可能なリサイクル技術を実現する。【解決手段】リサイクル方法は、カバーガラス２３と、電池層２１Ｂと、これらを密着する封止材２４と、を備える太陽電池モジュール２０に適用される。リサイクル方法は、カバーガラス２３と封止材２４との界面を所定の温度範囲に加熱し、その界面が所定の温度範囲を維持した状態で太陽電池モジュール２０の側面から封止材２４に力を加えて、その界面から封止材２４及び電池層２１Ｂを引き剥がす。【選択図】図１１
