ATW Technology has announced the signing of two major contracts with leading PV manufacturers, bringing the total value of contracts secured in the past few months to approximately 1.3 billion CNY. These contracts, valued at 900 million CNY and 400 million CNY respectively, involve the supply of ATW’s advanced monocrystal ingot pullers and auxiliary equipment, highlighting the growing confidence in the company’s manufacturing capabilities as it continues to build its reputation within the industry.
This momentum follows the launch of ATW subsidiary Songci Electromechanical (SCEC)’s third-generation monocrystalline ingot puller (SC-1600-Ⅲ), which addresses several manufacturing challenges, including issues such as high oxygen content in silicon rods, complex equipment upgrades and automation gaps, which have led to a growing demand for advanced solutions.
The SC-1600-Ⅲ delivers improved performance by reducing oxygen content in silicon rods to as low as 6ppm-7ppm. By optimizing dynamic and static heat fields and employing intelligent temperature control, the furnace significantly enhances crystal quality, industry tests indicating that this system can increase minority carrier lifetimes by 15-20% and improve downstream cell efficiency by 0.1-0.2%.
The product stands out with its advanced level of automation and intelligent technology, delivering a highly efficient and streamlined crystal pulling process. The integration of AI and a “one-click operation” feature allows for easy automation of the entire process, including material loading, crystal pulling, furnace shutdown and crystal extraction, minimizing manual intervention while optimizing performance.
Its sophisticated upper computer (HMI) software has also undergone a comprehensive upgrade based on user feedback, offering a dynamic display of real-time production data combined with process curves. This user-friendly interface provides operators with clear and intuitive access to critical information, with the advanced software logic ensuring precise control of both temperature and gas flow, reducing impurities and boosting crystal quality. With built-in digital technology, the system is also designed to integrate seamlessly with future intelligent factory automation.
