Multi-Si wafer (market for)

The activity generating the emissions is market for multi-Si wafer. The reference product is multi-Si wafer. 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 reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary market activity. Please refer to the ecoinvent documentation here for full details: https://ecoquery.ecoinvent.org/3.11/cutoff/dataset/10047/documentation.
