Tandem PV, a pioneer in American perovskite solar technology, has been named one of TIME Magazine’s Top GreenTech Companies of 2025 both in the United States and worldwide. This recognition follows the company’s recent $50 million Series A funding round to scale commercial production of its high-efficiency tandem solar panels and accelerate the transition to clean energy.
The honor reflects Tandem PV’s growing impact on the global renewable energy industry. TIME and Statista selected the top 250 greentech companies from more than 8,000 evaluated across over 30 countries and six continents. The list recognizes companies leading in environmental impact, financial strength, and innovation.
Tandem PV’s proprietary technology combines thin-film perovskite with conventional silicon solar cells to increase power output and reduce the cost of solar energy. The company’s panels currently achieve 28% efficiency and are projected to surpass 30% by late 2025, proving to be 30% more powerful than the average silicon solar panel. As Tandem PV expands domestic manufacturing, its technology offers a cost-effective, scalable solution for decarbonization and energy independence.
“Our team is obsessed with pushing the boundaries of science and technology to help achieve net zero and restore U.S. leadership in solar technology,” said Scott Wharton, CEO of Tandem PV. “Recognition by TIME alongside greentech innovators in AI, aerospace, and carbon capture is a testament to our collective work to build a more sustainable energy future.”
Tandem PV was also recognized last year in the “50 by 2050” list by Congruent Ventures, which highlights climate tech companies with strong potential to significantly drive carbon reduction over the next 25 years.
About Tandem PV
Tandem PV is driving the transition to a net-zero economy by developing state-of-the-art perovskite-based solar panels, which combine the durability and efficiency needed for broad scale deployment. The company will produce its solar panels domestically, to help the U.S. re-establish its energy industrial leadership and reduce dependency on foreign manufacturers. Its co-founder and CTO, Colin Bailie, developed the world's first perovskite-silicon tandem solar cell at Stanford University and launched the company through Activate, the U.S. Dept. of Energy startup accelerator. Tandem PV has raised a total of $83 million in venture capital, debt, and government funds from Eclipse, Constellation Energy, the Department of Energy and more.
