First Solar has signed a non-exclusive patent licensing agreement with Oxford PV, granting access to their perovskite technology for U.S. markets. This agreement supports First Solar's goal of advancing photovoltaic devices using perovskite semiconductors, excluding crystalline silicon.

The company reported $5.2 billion in annual sales for 2025, driven by a 24% increase in third-party module volume. For 2026, First Solar forecasts net sales between $4.9 billion and $5.2 billion. The company has invested over $2 billion in thin film research, operating a perovskite development line at its Ohio campus.

Additionally, First Solar filed a complaint with the U.S. International Trade Commission alleging infringement of its TOPCon patents against ten foreign manufacturers.
