India's Raana Secures Pre-Order for 1GW Ingot and Wafer Factory Equipment

en.Wedoany.com Reported - On November 7, Indian crystal growth equipment manufacturer Raana Semiconductors signed a pre-order equipment agreement with photovoltaic company SWELECT HHV Solar Photovoltaics, under which Raana will supply CZ12 Czochralski single-crystal growth equipment to the latter's planned 1GW ingot and wafer manufacturing facility. In addition to equipment supply, Raana will provide crystal growth process optimization, production recipe development, and personnel training, covering equipment operation, process commissioning, and subsequent production ramp-up.

The CZ12 equipment supplied adopts the Czochralski crystal growth technology route. In this process, high-purity polysilicon is loaded into a quartz crucible and heated to melting; under a protective atmosphere such as argon, a seed crystal is dipped into the silicon melt, and by controlling the rotation of the seed crystal and melt, the pulling speed, and temperature conditions, the silicon melt gradually solidifies along the seed crystal direction to form a monocrystalline silicon ingot with a continuous lattice structure. After subsequent orientation, slicing, and surface processing, the ingot can be made into wafers required for solar cell production.

Under the cooperation arrangement, Raana will also participate in SWELECT HHV's process recipe development and production parameter optimization, and provide equipment operation and maintenance training to the customer's technical personnel at its pilot plant. Technical support covers crystal growth process control, equipment operation management, and production process adjustment. In the ingot production stage, crystal quality, equipment continuous operating time, and product yield will directly affect subsequent wafer processing and factory capacity utilization.

SWELECT HHV Solar Photovoltaics is a wholly owned subsidiary of SWELECT Energy Systems. The equipment will be used for its planned 1GW ingot and wafer manufacturing facility. The project extends upstream to monocrystalline silicon ingot and wafer production, involving Czochralski single-crystal growth equipment, silicon material processing, and subsequent wafer manufacturing.

This pre-order also involves domestic Indian supply of photovoltaic manufacturing equipment. Raana has previously developed Czochralski single-crystal growth equipment and is advancing the commercialization of larger-size crystal growth equipment. In September 2026, the company announced a development plan for 12-inch single-crystal growth equipment and set a target that its equipment supply could support approximately 10GW of solar cell capacity over the next three years.
