Production Process of GYTECH Solar Wafer

1.Guangyi Silicon uses the most advanced high-capacity single-crystal pulling equipment, not only cost-effective production, but also the industry’s highest quality standards.

2.Through the strict inspection standards, the use of steel ingot side to side planer square shape of the handle.

3.Then, using high-precision cutting technology, through the wire saw (use a wire and formed by the silicon carbide slurry and ethylene glycol) will be cut into square wafers of silicon ingots.

4.After completion of cutting through the proprietary cleaning process to clean and dry wafers, and check to ensure it meets stringent customer characteristics and surface quality requirements.

5.Finally, check the quality of silicon wafers, packaged into boxes to customers or the Company concurrent battery manufacturing plant.
