OUR MISSION
Restoring U.S. Leadership for the
Next Era of Solar Manufacturing
As global demand for energy surges, driven by insatiable AI needs, the United States must reduce its reliance on foreign energy sources. Solar power is already the world’s fastest-growing energy source, and to secure U.S. energy independence and dominance, it must be even more efficient and scalable. Tandem PV is developing a new generation of solar panels designed for commercial manufacturing in the U.S. that are more powerful, durable, and cost-effective.
"Tandem PV’s impressive durability and efficiency is unmatched in the market, and it couldn’t come at a more critical time."

DISRUPTIVE TECHNOLOGY
Efficiency that delivers more power
Durability built for long-term performance
​
Perovskite is the power behind our panels, capturing wavelengths of light that conventional silicon solar panels do not efficiently convert to electricity.
​
Tandem PV’s design boosts the output of conventional solar modules by combining them with thin-film perovskite. These tandem perovskite panels have already reached 30% efficiency, with a clear path to further gains as the technology advances. Compared with conventional panels, this translates into roughly 40% more power in the same form factor, transforming the economics of utility-scale solar projects. We have also demonstrated durability that meets the lifetime expectations for long-term solar deployment, with accelerated testing showing less than 1% annual degradation.
​
LOWER COST
Our tandem approach delivers substantially more power from the same panel footprint at a similar cost per watt, reshaping project-level economics for solar developers.
Today, modules account for a shrinking share of overall solar costs, with labor, land, and installation now accounting for the majority of solar deployment expenses. By producing more energy from the same number of panels, Tandem PV reduces total cost of ownership where it matters most.
We are also developing a robust portfolio of patents in core perovskite-layer technology, system design, and durability performance to protect and extend these advantages as we scale.
CUTTING-EDGE
DURABILITY
Perovskites can degrade when exposed to moisture, oxygen, light, heat, or voltage — just as conventional silicon panels can. Drawing on years of solar industry experience, patented technology, and design innovations, we have demonstrated extended durability suitable for long-term deployment, supported by accelerated testing showing less than 1% annual degradation. This level of durability aligns with today’s leading silicon modules.
Our Vision
Tandem PV is building toward a future where American-made solar technology restores U.S. leadership in clean energy, drives down the cost of power, and fuels the next wave of innovation, including the AI revolution.
By lowering the costs of solar power, Tandem PV helps accelerate deployment at gigawatt scale. This strengthens energy security, revitalizes domestic manufacturing, and drives the emissions reductions needed to address climate change.

WORK WITH US
Our Customers
Independent Power Producers (IPPs)
Tandem PV manufactures high-efficiency, standard-size solar panels built to integrate seamlessly into existing utility-scale infrastructure. Backed by decades of solar industry experience and $87 million in funding from leading investors and partners, our panels deliver more power at the same price per watt, reducing labor, installation, and land costs, and ultimately lowering the total cost of ownership. We are initially focused on utility-scale deployments, with IPPs as our first customers.
​
Solar Manufacturers
Tandem PV also partners with established solar manufacturers seeking to bring tandem solar products to market. Through our perovskite technology, process expertise, and materials know-how, we enable manufacturers to integrate a perovskite layer onto existing silicon panel designs — accelerating commercialization of higher-efficiency modules without reinventing their existing manufacturing stack.​
