First Solar has signed a non-exclusive patent licensing agreement with CubicPV, gaining access to the company’s issued and pending US patents covering perovskite solar technology. The agreement allows First Solar to continue developing perovskite-based photovoltaic (PV) devices for the US utility-scale, commercial and industrial, and residential markets. First Solar has an existing 3.3 GW capacity plant in India as well.
The licence covers the domestic sale and distribution of products developed using the technology. Financial details and other terms of the agreement have not been disclosed.
The agreement comes as solar manufacturers explore perovskite materials for next-generation PV cells, particularly tandem configurations that combine perovskite with conventional silicon to improve solar conversion efficiency.
First Solar is developing perovskite-based PV modules at its research and development facility in Perrysburg, Ohio. Its existing development line produces small-format modules and has been used to assess initial efficiency, stability and manufacturability.
The company is also investing in a larger pilot line in Ohio, which will produce modules equivalent in dimensions to its Series 6 modules. The facility is expected to become operational in the first half of 2027.
First Solar has invested more than $2 billion in thin-film research and development, including its perovskite programme. However, the company has not disclosed a commercial production timeline for its perovskite modules.
Perovskite materials have attracted interest for their potential to improve solar cell efficiency, particularly when combined with silicon in tandem configurations.
In these cells, the perovskite layer absorbs higher-energy portions of sunlight, while the underlying silicon layer captures lower-energy light. This allows the two materials to utilise a broader portion of the solar spectrum than conventional single-junction silicon cells.
However, commercial deployment remains dependent on addressing challenges related to long-term stability, moisture and heat resistance, manufacturing consistency and production costs.
The licensing agreement also highlights the role of intellectual property in the development of emerging solar technologies. CubicPV has spent more than a decade developing perovskite technology and building its patent portfolio.
