“What is commercially available today passed mass production verification two to three years ago. The eight new technologies unveiled today reflect five to ten years of R&D, and what’s still in the lab, not yet disclosed, is already shaping the next decade,” said Li Zhenguo, founder and CTO of LONGi. He outlined the company’s full-cycle innovation philosophy at the 2026 PV & Energy Storage Innovation Technology Launch co-hosted with Shanghai Jiao Tong University on 14 July.

At the event, LONGi unveiled what it is dubbing its “technology forest” suite of new innovations, with eight cutting-edge technologies making a debut. Leading the lineup is the ACM (Advanced Contact Matrix) nano-alloy matrix contact technology, which LONGi announced last week had reached gigawatt-scale mass production at its Xixian base. As the core pillar of the technology ecosystem, ACM tackles long-standing PV metallisation bottlenecks and offers a mass-production solution to the industry’s trilemma of high efficiency, low cost and high reliability.
