Maxeon Solar Technologies Initiates TOPCon Patent Infringement Lawsuit Against Hanwha Q CELLS

PVTIME – Maxeon Solar Technologies, Ltd. (NASDAQ:MAXN), a global leader in solar innovation and channels, today announced that it has initiated a patent infringement lawsuit in the Eastern District of Texas against Hanwha Q CELLS, alleging their infringement of Maxeon patents relating to TOPCon (Tunnel Oxide Passivated Contact) solar cell technology.

Maxeon’s leadership in solar technology is the result of nearly 40 years of research of development and over half a billion dollars of investment since 2007, leading to major advances in solar cell and panel efficiency, performance, and cost. The Company has a global patent portfolio of over 1,650 granted patents and more than 330 pending patent applications protecting the innovations underpinning its IBC (Interdigitated Back Contact), Shingled Hypercell, and TOPCon technologies. 

“In November 2023, Maxeon initiated a TOPCon patent infringement investigation in the United States, and this lawsuit against Hanwha Q CELLS, along with recent similar actions against Canadian Solar, Inc. and REC Solar Holdings AS, are results of that investigation,” said Marc Robinson, Maxeon’s Associate General Counsel. “Maxeon has the responsibility to protect the leadership position it has earned from its substantial R&D investments and will continue to enforce its patent rights against those who are attempting to sell infringing products in the U.S. and its other markets.”
