The non-exclusive patent license gives First Solar access to Oxford PV’s existing and currently pending technology patents in the US.
February 26, 2026
UK-based perovskite solar firm Oxford PV has agreed a licensing deal with US cadmium telluride (CdTe) thin-film module manufacturer First Solar.
The non-exclusive patent license gives First Solar access to Oxford PV’s existing and currently pending technology patents in the US. The company said the license covers “the potential manufacturing and distribution” of perovskite products in the US and excludes crystalline silicon semiconductors.
First Solar CEO Mark Widmar said the license would allow the firm to “continue pursuing viable pathways to manufacturing and commercialising thin film-perovskite products,” and that it “reflects the confidence we have in our R&D [research and development] team’s progress in developing an efficient, stable and manufacturable perovskite device.”
First Solar said it had invested US$2 billion in thin-film R&D, including a “focus” on perovskites. This includes a perovskite development line at its facility in Perrysburg, Ohio, which it said produces “small form-factor modules featuring a perovskite semiconductor” to support the company’s work on the efficiency and stability of perovskite solar products.

Oxford PV has emerged as one of the foremost companies in the silicon-perovskite tandem solar industry. The firm said it had shipped the first commercial perovskite tandem solar modules to an unnamed US client in September 2024, and has since signed another exclusive patent licensing agreement with Chinese solar manufacturing giant Trinasolar for the production of perovskite products in China.
“Strong intellectual property frameworks are essential to supporting innovation at scale across the solar industry,” said David Ward, CEO of Oxford PV. “Agreements like this, building on earlier industry validation, reflect growing confidence in perovskite-based photovoltaics—the next generation of solar technology we have been developing for over a decade—and support its advancement in the US market.”
