ATW Technology has announced agreements with two leading solar manufacturers to upgrade their existing production lines with its innovative 0BB (zero busbar) stringer technology. The combined upgrade capacity of approximately 20GW marks a major milestone for the company in the commercialization of its 0BB technology for TOPCon modules.
“This technology breakthrough represents more than just an incremental improvement,” commented an ATW spokesperson. “It’s a fundamental shift in solar module manufacturing that offers both technical and economic advantages.”
The company’s newest ultra-high-speed 0BB stringer, launched in mid-2024, showcases ATW’s technological expertise, backed by over 120 patents and three years of intensive R&D involving some 100 researchers. The system’s versatile platform architecture supports multiple process technologies including TOPCon, HJT and BC, with precise temperature control capabilities accommodating a range of adhesive systems and curing processes.
What sets the company’s approach apart is its modular upgrade strategy for existing SMBB equipment, allowing manufacturers to transition to 0BB technology without the need for the complete replacement of a production line. This cost-effective solution has attracted significant industry interest, with additional upgrade projects totalling over 60GW currently under negotiation.
Looking ahead, ATW Technology continues to develop upgrade solutions for BC (back contact) solar cell technology while maintaining its focus on customer-driven innovation. As the solar industry continues its pursuit of higher efficiency and lower costs, the company commitment to advancing manufacturing technology positions it as a key enabler of sustainable energy development.
