Tandem PV, a company at the forefront of next-generation solar technology, has received a $4 million grant from the California Energy Commission (CEC) to support the commercialization of its high-efficiency perovskite-silicon tandem solar panels. This funding will enable the company to conduct comprehensive third-party testing and validation of its technology as it moves closer to full-scale deployment and domestic manufacturing.
Tandem PVโs solar panels are built using a dual-layer structure that combines a thin layer of perovskite, a material known for its excellent light absorption, with traditional silicon solar cells. This advanced design enhances energy output while reducing overall solar energy costs. The panels currently reach an impressive 28% efficiency and produce up to 30% more power than conventional silicon-based panels, making them some of the most powerful and efficient in development globally.
The grant from the CEC will be used to assess the panelsโ performance under real-world conditions through partnerships with independent laboratories and technical institutions. The testing will focus on long-term durability, environmental resistance, and consistent energy generation. These evaluations will complement Tandem PVโs internal laboratory results, which have already demonstrated strong efficiency levels and long-term performance stability.
Colin Bailie, Founder and CTO, Tandem PV, stated, โThis award accelerates our durability testing to bring us closer to delivering a new standard for clean energy and delivering high-efficiency solar thatโs proven, reliable, and ready for the market. Weโre grateful to the California Energy Commissionโs leadership in investing in the technologies that will power the countryโs clean energy future.โ
Scott Wharton, CEO of Tandem PV, stated, โCalifornia has long been a global leader in solar innovation, and weโre proud to be part of the next chapter. This support from the CEC signals strong momentum for tandem solar technology and helps ensure that the next wave of clean energy breakthroughs are developed and manufactured here in the U.S.โ
This grant follows an earlier award of $5.2 million that Tandem PV received from the U.S. Department of Energy in late 2024. That funding was part of the DOEโs thin-film solar initiative and is being used to scale up the manufacturing and commercialization of the companyโs tandem solar panels. Together, these grants reflect growing confidence in Tandem PVโs technology and its potential to play a key role in making solar energy more efficient, scalable, and cost-effective. The companyโs innovations support broader goals of U.S. energy independence and decarbonization, especially as it ramps up domestic production of advanced solar solutions.
