AI Customer ServiceThe glass, backsheet, and solar cells are bonded by EVA film, and the main separation methods include mechanical methods, pyrolysis, and chemical methods (Dias et al., 2021, Granata et al., 2014, Tammaro et al., 2015). The mechanical method separates waste PV modules through crushing and subsequent sorting (Pagnanelli et al., 2017).
The peeling process relies on the phenomenon of water-assisted subcritical debonding at interface between Ni and silicon dioxide (SiO 2 ), which separates the metallic layer together with TFSCs from the original Si wafer 14, 15.
With experimental research in the last decade, borrowing from theory developed about three decades ago, controlled spalling has shown its capacity to produce high-performance III-V solar cells by separating device layers from their host substrates in a fast process.
The experimental results show that temperature has a promotion effect on the glass peeling rate. An ultrasonic field also facilitates the separation of different layers, and the solid/liquid ratio has less effect on the peeling rate of the PV module glass. 3.4. Mechanism of the layer separation using EGDA
The laser energy will be absorbed by the back metal (Al and Ag) electrode, leading to a temperature rise across the solar cell/EVA interface. The temperature rise can weaken the adhesive strength between the solar cell and EVA, which will make it easy to peel the EVA layer off from the solar cell.
Furthermore, the tough stressor layer is able to support the inherently fragile semiconductor layers, forming a layered composite, which can improve the overall mechanical stiffness of the solar cells and their resistance to fracture.
