Disassembly is the first step for any PV module recycling process, which takes apart the aluminium frame from the waste module for recycling. Delamination is the step to open the laminated structure of the module and is the most challenging part, thus resulting in a detrimental impact on processing complexity, pollution, and cost.
Module disassembly consists of the removal of the aluminum frame, junction boxes, and cables as pictured in Figure 3, and also produces a laminate structure of the solar glass, encapsulant, solar cells, and backsheet.
In general, value-recycling follows three steps: disassembly, delamination, material sorting, and material extraction, as shown in Fig. 2. Disassembly is the first step for any PV module recycling process, which takes apart the aluminium frame from the waste module for recycling.
