Customer ServiceAt present, only top producers in China are able to produce silicon good enough for monocrystalline solar cells. As a result, Chinese PV players are dependent on imports of high-quality polysilicon, mainly from Wacker and OCI. The Chinese solar industry is also pushing monocrystalline technology.
Chen et al. (2016) evaluated the environmental impact of the production process of monocrystalline silicon PV cells in China, which showed that due to the consumption of silver paste, electricity and glass, the impacts caused by human toxicity, marine ecotoxicity and metal depletion are dominant to the overall environmental impact.
It is mainly because the total environmental impact of the life cycle of polycrystalline silicon PV panels is higher than that of monocrystalline silicon PV panels, and the higher IPCE brings about the relatively higher cost of monocrystalline silicon PV panels.
The production of silicon material is expected to reach 1.5 million tonnes in China by 2023, which is equivalent to approximately 625GW of wafers. The estimated production capacity of wafers is projected to exceed 900GW, with a demand for 460GW of wafers for PV installation.
As reported by China Photovoltaic Industry Association ( CPIA, 2022 ), in 2021, the average IPCE for monocrystalline silicon PV modules in China in 2021 was about 22.40% and for polycrystalline silicon PV modules about 19.5%.
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.
