Included activities starts

The activity begins when high-purity polysilicon, diamond wire, and other raw and auxiliary materials enter the factory gate.

Included activities ends

The activity ends with the production of wafers.

Description

Silicon wafers can be used in the production of photovoltaic cells, with an average area density of approximately 469.09 g/m². If the specific type of crystalline silicon wafer cannot be clearly defined, this dataset may be used. The dataset represents a weighted average of the following datasets: "monocrystalline silicon wafer, unspecified, for monocrystalline photovoltaic cells" and "polycrystalline silicon wafer, for polycrystalline photovoltaic cells." Detailed technical descriptions, system boundaries, and related information can be found in the respective production datasets for each type of crystalline silicon wafer. Infrastructure such as manufacturing equipment for production and factory construction are not included within the system boundaries of this dataset.

Activity Description

The production of silicon wafers includes the processes of ingot/rod, squaring, and wafering.

Process Description

The product represents 1 m² of silicon wafers for photovoltaic cells, which are square-shaped wafers cut from silicon ingots.
