Polysilicon photovoltaic (PV) modules are about to enter the end-of-life (EOL) stage on a large scale, and making the exploration of effective recycling methods and comprehensive evaluations their environmental impact through life cycle assessment (LCA) are key issues that need to be urgently tackled.
But, right now, recycling silicon from old PV modules isn't working well. While making the silicon wafers, the loss is more than 40% of the silicon. Advancements in recycling silicon have made progress, achieving a 60% recovery rate from leftover PV modules . However, this rate is not as high as it could be.
Most of the materials of polysilicon PV modules are reusable, including aluminum, glass, silver, copper, silicon and so on . Recycling of waste polysilicon PV modules can usually be divided into three stages: dismantling the aluminum frame and junction box, delamination and component separation.
Crystal silicon cells accounted for more than 95% of this capacity [1, 2]. Figure 1 illustrates the value chain of the silicon photovoltaic industry, ranging from industrial silicon through polysilicon, monocrystalline silicon, silicon wafer cutting, solar cell production, and finally photovoltaic (PV) module assembly.
