Overview
- Tandem PV opened a 65,000-square-foot demonstration plant in Fremont, California, that can produce about 40 MW of perovskite-silicon panels each year.
- The panels add a thin perovskite layer on top of a silicon cell to capture more of the sun’s spectrum and raise power output from the same area.
- Internal tests show 29.7% efficiency, with accelerated life testing indicating less than 1% average annual power loss as the company targets 25-plus years of field performance.
- The line has begun turning out initial modules, with customer validation shipments planned later this year and first commercial sales expected in 2026, followed by a push to high-volume manufacturing in 2028.
- Federal and state support, including from the U.S. Department of Energy and the California Energy Commission, underpins the scale-up, though broad adoption will depend on independent proof of long-term durability.
