Today, Tandem PV is opening an automated solar perovskite factory in CA. (Canary Media)
The product: The company’s perovskite-coated glass (placed on top of conventional silicon cells) can boost efficiency from 22% to 30%, per CEO Scott Wharton. That's a third more energy from the same footprint, with knock-on savings on land, labor, steel, and trackers.
The caveats: Panels currently churned out at the 65K-sqft facility are just a quarter of utility-scale dimensions. The factory’s annual capacity tops out at 40 MW, and durability—a historical weak point—still has to hold up in field trials with a "who's who" of US developers. Full-size panels are targeted for 2028.
Why it matters: US solar manufacturing has largely replicated what China already makes (on a smaller scale). Now, perovskites could help speed up the transition to domestic clean energy that’s independent of China's silicon supply chain.
