Tandem cell production
Our site in Brandenburg-an-der-Havel, near Berlin, Germany, houses the world’s first volume manufacturing line for perovskite-on-silicon tandem solar cells. Our line will commence production in 2023.

Since 2017, the facility has supported the transfer of our technology from our lab to industrial equipment and processes on full-sized wafers. The production line, which is currently ramping to high-volume, produces our commercial M6 tandem wafer product.
