Our site in Brandenburg-an-der-Havel houses the world’s first volume manufacturing line for perovskite-on-silicon tandem solar cells. We are installing a silicon heterojunction solar cell line enhanced with production equipment for the perovskite top cell. Our line will commence production in 2023.
Pilot production

Our low-volume production line manufactures commercial-sized perovskite-on-silicon tandem solar cells for qualification.

Since 2016, the facility has supported the transfer of our technology from our lab to industrial equipment and processes, in preparation for mass production.
