High-quality silicon wafers for global cell manufacturers.

Stellar PV will produce silicon ingots and wafers to the standards required by leading cell manufacturers in key markets.

Where we sit in the value chain.

The journey from raw mineral to finished module involves seven distinct stages. The midstream stages, ingots and wafers, are where most of the value is created. Stellar PV operates at this critical step.

Our product.

Stellar PV manufactures mono-crystalline silicon ingots and wafers in the formats specified by leading cell manufacturers.

Ingots are cylindrical and squared mono-crystalline silicon ingots, produced using the Czochralski process.

Wafers are precision-sliced silicon wafers in M10 and G12 formats, manufactured to global industry standards for thickness, flatness, and purity.

Polysilicon

POLYSILICON FEEDSTOCK.

Semiconductor-grade polysilicon is sourced from trusted suppliers and prepared for crystal growth. 

ingot

INGOT GROWTH.

Polysilicon is melted and pulled into mono-crystalline ingots using the Czochralski process, producing the crystal uniformity essential for high-efficiency cells.

Silicon Brick

SQUARING.

Cylindrical ingots are precision-squared to the M10 or G12 format required by cell manufacturers.

wafer

WAFER SLICING

Squared ingots are sliced using diamond wire technology into thin wafers of consistent thickness, flatness, and surface quality.

Built for performance, traceability, and integrity.

Stellar PV’s facility is designed to meet the requirements of buyers who care as much about how a product is made as the product itself.

Technical performance.

Wafers manufactured to the purity, uniformity, and thickness standards required for high-efficiency cell production.

Traceability by design.

Auditable inputs and process records support the supply chain integrity requirements of allied procurement frameworks.

Low-carbon manufacturing.

Renewable energy integration and circular process design reduce the embodied carbon of every wafer produced.

Resource efficiency.

Polysilicon, argon, water, and kerf recycling minimise waste and operating cost across the facility.

Capacity & scale

The facility is designed for an initial capacity of two gigawatts of annual wafer production, with site and process configuration that allows for future expansion. Output is supplied to cell manufacturers in allied markets under long-term commercial arrangements.

A Trusted Source of Supply

Stellar PV is establishing a credible, high-integrity silicon manufacturing capability in Australia, supplying cell manufacturers across global markets.
