Use advice for data set
When using this LCA data set for evaluating the environmental impacts of PV systems, it is crucial to apply the functional unit of 1 kWh based on a multi-Si PV module. Care should be taken to ensure that the scope of the assessment includes all relevant stages of the multi-Si PV module's life cycle, including production, use, and end-of-life management. Data users should also consider the technological specificity of the Chinese PV industry as described in the report 'Clean Production of Solar PV in China' and reference the MG-Si production data sourced from contemporary Chinese literature.

Technical purpose
The multi-crystalline silicon (multi-Si) wafer slicing process using multi wire saw is intended for the production of solar-grade wafers for use in photovoltaic (PV) systems. These wafers are the foundation for creating multi-Si ingots, cells, and modules that are essential components in the assembly of PV panels designed to convert sunlight into electrical energy. This technology is predominantly utilized for the manufacture of multi-Si PV modules within the Chinese PV industry, contributing to its sustainable development.
