What They Do
Tandem PV specializes in the development and manufacturing of perovskite-silicon tandem solar panels, focusing on next-generation solar technology rather than general renewable energy development (source: linkedin.com). Their core innovation lies in pairing a thin perovskite layer with conventional silicon cells, creating a dual-layer architecture that significantly boosts power output and improves cost per watt, designed for high-volume production and broad utility-scale deployment (source: tandempv.com). The company’s panels currently achieve approximately 28% efficiency, making them about 30% more powerful than average silicon solar panels, with a strong emphasis on durability and suitability for large-scale projects (source: tandempv.com). Tandem PV’s mission centers on commercializing U.S.-manufactured solar panels to strengthen domestic supply chains and solar leadership, distinguishing itself by focusing on manufacturing scale-up rather than software or project development services (source: tandempv.com).
Projects & Track Record
Tandem PV’s landmark achievement is the opening of its commercial demonstration factory in Fremont, California, in April 2026, marking a critical step toward commercializing U.S.-manufactured next-generation solar panels for utility-scale projects (source: tandempv.com). In August 2026, the company was selected for the U.S. Department of Energy’s ARPA-E SCALEUP Ready program, securing approximately $7.7 million in funding to accelerate the scale-up and commercialization of its perovskite-silicon tandem technology (source: tandempv.com). While Tandem PV has not publicly disclosed a broad portfolio of named utility projects, it consistently targets utility-scale solar and commercial-grade panels for both residential and large-scale applications (source: tandempv.com). The company’s partnerships and investor base include notable entities such as Eclipse, Constellation Energy, the U.S. Department of Energy, the California Energy Commission, Planetary Technologies, Trellis Climate, Uncorrelated Ventures, CSC Leasing, and Stifel Bank, reflecting strong industry and financial support (source: tandempv.com).
Recent Developments
In March 2025, Tandem PV announced a $50 million Series A and debt financing round led by Eclipse to fund its commercial-scale manufacturing facility in the United States (source: tandempv.com). By July 2025, the company secured a $4 million grant from the California Energy Commission to support third-party testing and validation of its tandem solar panels, advancing commercial readiness (source: tandempv.com). Leadership appointments in 2025 included Frank Blohm as vice president of operations and Dr. Robert Meagley as vice president of quality, both roles aimed at supporting manufacturing scale-up and quality assurance (source: tandempv.com). In April 2026, the company opened its Fremont factory, and in June 2026, former U.S. Energy Secretary Jennifer Granholm joined its board of directors, enhancing its leadership profile (source: tandempv.com). August 2026 saw the acquisition of nexTC to internalize critical coating technology, followed by the ARPA-E SCALEUP Ready award announcement, further accelerating its manufacturing capabilities (source: tandempv.com). Tandem PV was also recognized by TIME as one of America’s Top GreenTech Companies of 2026 for the third consecutive year and was named to the “50 by 2050” list in 2025, underscoring its industry leadership (source: tandempv.com).
