| Use advice for data set | For life cycle assessment (LCA) practitioners, this data set can be applied to evaluate the environmental impact of the production stage of mono-Si and multi-Si photovoltaic systems in China. When using this data, consider the methodological boundaries such as system boundary, specific inputs like silica, charcoal, petroleum coke, and the choice of technological routes. Take into account the recycling and disposal processes of the silicon and photovoltaic systems, reflecting them correctly in the LCA model. The functional unit for this assessment is defined as 1 kWp of photovoltaic system capacity. |
| Technical purpose of product or process | The industrial process described is the production of industrial silicon using 97% purity level through carbon reduction methods. This high-grade silicon is specifically employed in the manufacturing of monocrystalline and multi-crystalline silicon photovoltaic systems. Such silicon is integral to the PV industry, where it is used to produce the semiconductor wafers that form the core of solar panels. |
