The life cycle of a Polycrystalline silicon PV module starts with the mining and refining of silica (quartz) ( Stoppato, 2008, Raugei et al., 2007a ). Silica is reduced with the use of carbon and the reduction step is either followed or preceded by a purification step.
The primary challenges in recycling silicon solar panels are multifaceted, encompassing technical, environmental, and economic aspects. The production of harmful dust, the potential release of hazardous substances, and the environmental impact of various recycling processes are key concerns that need addressing.
Figure 5 shows the environmental impact of polycrystalline and monocrystalline silicon cell manufacturing in the US and China. It is notable that the amount of environmental impact in the manufacturing stage is higher than in the processing stage. The highest pollution in PV manufacturing corresponds to SO x, NO x, followed by PM 2.5 and CO.
The economic value of the valuable metals is $13.62/m 2, resulting in a profit of $1.19 per recycling of 1 m 2 of crystalline silicon PV panels. The breakdown of total revenue generated after selling the recovered valuable materials is as follows: 46% (aluminium), 25% (silver), 15% (glass), 11% (silicon), and 3% (copper).
In this review article, the complete recycling process is systematically summarized into two main sections: disassembly and delamination treatment for silicon-based PV panels, involving physical, thermal, and chemical treatment, and the retrieval of valuable metals (silicon, silver, copper, tin, etc.).
