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 detailed calculations show around 2.7–4.4 and 1.3–2.4 times increase in 2030 compared with 2010 estimated in the amount of generated pollution through polycrystalline and monocrystalline silicon PV production in China and the US, respectively.
Data are available in Supplementary Information (#5). The environmental costs associated with silicon flows used in solar PV manufacturing include factors such as energy consumption, water usage, emissions of greenhouse gases and other pollutants, as well as the impact on local ecosystems and communities.
Nonetheless, assessment of environmental impact of production processes through the PV technology supply chain is essential to ensure its sustainability and this work outlines the environmental cost of solar PV supply chain for the US and China as leading global PV manufacturers with significant local reserves of silicon.
Stamford and Azapagic (2018) [ 17] studied the environmental effects of silicon-based PV systems in the UK, Spain, and China based on a life cycle evaluation approach to explore PV systems’ impact on the environment. They found that the manufacturing shift from Europe to China brought adverse environmental effects to China.
The monocrystalline silicon solar cells are quite costly and there is little room for a price reduction due to the high price of monocrystalline silicon materials and the complex cell manufacturing process [ 23 ]. As a result, in industrial production, polysilicon has replaced monocrystalline silicon.
