Solar module manufacturer Heliene Inc. and perovskite solar firm Caelux Corp. have begun commercial production of their Hybrid-Tandem solar module in the U.S. market, officials say.
Boasting module conversion efficiencies of up to 27%, the perovskite and silicon module technology combines Caelux’s Energy Producing Glass product with Heliene’s silicon PV module platform. Bringing the two together creates a solar module with two separate layers of power generation, delivering higher power density than ever before.
“One of the advantages of Caelux’s technology is that we can integrate its Energy Producing Glass into our existing manufacturing lines without having to build an entirely new production setup,” says Heliene CEO Martin Pochtaruk. “With both companies manufacturing in the U.S., we’re bringing together two fully domestic supply chains to advance what’s possible with American-made solar, besides the fact that partnering with true friends also makes it fun.”
Combining the two layers of solar power generation creates a slew of new opportunities, Heliene representatives say. The Hybrid-Tandem module is capable of generating up to 20% more energy than a more conventional N type module, far exceeding the limits of silicon-only PV technology. Using the new hybrid technology, customers can achieve the same energy output in significantly less space, the companies add.
Commercial and utility-scale customers will benefit most heavily from the new product, according to Heliene. The company says the module’s efficiency levels in tight spaces are especially useful for rooftop installations, generating more energy over less area.
Additionally, the module presents a major cost saving opportunity, stemming from Caelux’s Energy Producing Glass. The product’s step-function improvement in efficiency across any and all project types paves the way for cost-effective power generation, the companies say, which will eventually pay for itself.
“Heliene is a true leader in U.S. manufacturing, and we share a belief that when we lead the market, our customers win,” says Caelux CEO Scott Graybeal. “Together, we’re commercializing ultra-high-efficiency solar modules that will set a new bar for American-made solar.”
The two companies have already entered into a commercialization agreement as of Nov. 10, officials say. The multi-year, multi-gigawatt partnership will see Heliene producing the new module at its facility in Mountain Iron, Minnesota, with first deliveries available by 2027.
