Oxford PV (Oxford Photovoltaics Limited) is a British solar technology company that develops and manufactures perovskite-on-silicon tandem solar cells and modules. The company was founded in 2010 as a spin-out from the University of Oxford by Professor Henry Snaith and Kevin Arthur, and the university still holds an ownership stake. Its tandem cells coat a thin perovskite layer on the front of a conventional silicon cell, allowing the two layers to absorb different parts of the light spectrum.

The company operates a research and development site in Yarnton near Oxford, UK, and a pilot and production line in Brandenburg an der Havel, Germany, where a former factory was acquired in 2016. In September 2024 it shipped the world's first commercial perovskite-silicon tandem modules, to a US customer for a utility-scale project. Its module efficiency reached 25% in 2024 and 26.9% in a residential-size module that year, and its roadmap targets 27% by 2027 and 30% by 2030. The company reports more than 400 granted patents and a portfolio focused on perovskite PV.

Oxford PV targets utility-scale, buildings, electric vehicles and aerospace applications, and pursues a mainstream manufacturing model alongside specialty applications and patent licensing. Licensing agreements include an exclusive deal with Trinasolar for the Chinese market in April 2025 and a non-exclusive US patent licence with First Solar in February 2026. The company has joined the UK-led SUITE project on solar panels for electric vehicles.

Investors include Equinor Ventures, Legal & General Capital, Goldwind and Meyer Burger, which became the largest shareholder in 2019. The company has also received European Investment Bank financing and German and UK government grants.
