First Solar Licenses TOPCon Patents to Talon PV for New US Solar Manufacturing Plant

Agreement paves way for American TOPCon crystalline silicon PV cell manufacturing

TEMPE, Ariz. & HOUSTON--(BUSINESS WIRE)-- Talon PV, a US-based manufacturer of crystalline silicon (c-Si) photovoltaic (PV) solar cells, has secured the license for crucial Tunnel Oxide Passivated Contact (TOPCon) cell manufacturing patents from First Solar, Inc. (Nasdaq: FSLR), America’s leading solar technology and manufacturing company. The terms of the agreement were not disclosed.

Talon's US-based N-type TOPCon cell manufacturing facility is scheduled to commence operations in the first quarter of 2026, adding 4 gigawatts (GW) of annual American c-Si solar cell production capacity by first quarter of 2027.

“We’re thrilled to partner with First Solar, America’s flagship solar technology company, to ensure that we can differentiate ourselves from other cell manufacturers not just by manufacturing in the United States but also in offering our customers the peace of mind that comes with procuring cells that don’t infringe on other companies’ intellectual property,” said Adam Tesanovich, Chief Executive Officer, Talon PV. “Securing this license keeps us on track to produce American-made TOPCon cells next year, enabling the onshoring of a critical component of the crystalline silicon solar value chain.”

First Solar obtained the US TOPCon patents and related international counterparts through its 2013 acquisition of TetraSun, Inc. The patents include issued patents in the United States, Australia, Canada, China, the European Union, Hong Kong, Japan, Mexico, Malaysia, Singapore, South Korea, the United Arab Emirates, and Vietnam with validities extending to 2030 and beyond. The portfolio also includes pending patent applications in the European Union, Japan, Hong Kong, United Arab Emirates, and Vietnam.

“We have long advocated for the development of a diverse, competitive American solar manufacturing industry, and we’re pleased to support a fellow American company’s efforts to produce crystalline silicon solar cells in the US,” said Jason Dymbort, Executive Vice President, General Counsel and Secretary, First Solar. “We are encouraged to find that manufacturers like Talon PV are committed to ensuring their freedom to manufacture by operating within the framework of the law and ensuring that their products don’t infringe on our patents. Our decision to license our intellectual property reflects our willingness to work with companies that respect the law.”
