Multi-si wafer (multi-Si wafer production)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. This product represents 1 m2 of multi-Si wafer used to produce photovoltaic cells. Wafers are round disks cut from pure silicon ingots. Multi-Si or polycrystalline silicon consists of many small silicon crystals compared to single-Si that consist of one single continuous crystal. Multi-Si cells are usually less efficient than single-Si photovoltaic cells The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
