Polycrystalline Silicon

The fundamental input of photovoltaic cell and module production: solar-grade polysilicon.

Polycrystalline Silicon

In the crystal growth stage, purified silicon takes on a polycrystalline structure. Solar-grade polysilicon is the raw material for monocrystalline ingot pulling and wafer production, and one of the most critical links in the photovoltaic supply chain.

Product quality at this stage is defined by purity, crystal structure and lot homogeneity. Each lot is documented according to our customers' qualification requirements.
