Global SolaEon Shatters Perovskite Barrier With 20.7% Square-Metre Efficiency Record

• SolaEon’s 0.72 m² perovskite panel posts a certified 20.7 % efficiency, breaking the 20 % barrier at commercial scale and signalling perovskite’s market arrival.

If the perovskite revolution ever needed a defining milestone, it arrived this week. China’s SolaEon has unveiled a commercial-format module—measuring 1.2 m × 0.6 m—that hits a certified 20.7 % power-conversion efficiency, the first time any perovskite panel has cleared the vaunted 20-per-cent hurdle at square-metre scale. The 0.72 m² single-junction device delivers 149 W, and the figure has been signed off by the China National Institute of Metrology, giving the claim serious global standing.

How big a leap is that?

Only last year SolaEon grabbed headlines with a 19.2 % mark that already topped the U.S. NREL champion charts for large-area perovskite modules. Jumping another full percentage point in just twelve months underscores how fast material science and process control are maturing inside the company’s labs.

Scaling, not just lab tricks

Breakthroughs often languish in R&D purgatory, but SolaEon is rolling this tech off a brand-new 200-MW production line commissioned in March. Management says the line is already shipping commercial orders with yields above 95 %, suggesting the record is less a one-off achievement than a harbinger of volume supply.

Why 20 % matters

Crossing the 20-per-cent threshold takes perovskite into territory long dominated by mainstream mono-PERC silicon modules. When paired with perovskite’s thin-film flexibility, lower temperature processing and richer light absorption, the new efficiency shrinks the performance gap while preserving cost advantages. Analysts tracking the technology say 20 %-plus is the psychological level at which bankability conversations with project financiers begin to tilt in perovskite’s favour.

What’s next?

SolaEon’s April announcement of a 31.38 % all-perovskite tandem cell hints at where the company—and the sector—are heading: multilayer architectures that stack efficiencies rather than chase incremental gains. For now, though, commercial buyers can tap into a module that finally translates perovskite hype into utility-scale reality. Expect rooftop integrators and lightweight BIPV designers to be early adopters, followed quickly by ground-mount developers looking to shave balance-of-system costs.

Industry take-away

In a PV market hungry for alternatives to silicon and eager to diversify supply chains, SolaEon’s 20.7 % milestone is more than a record—it’s a marker that perovskite is exiting the lab and entering the gigawatt league. Whether rivals can match the pace will shape the next decade of solar manufacturing.
