Perovskite/silicon tandem solar cells on the way from the laboratory to production

A cluster facility set up at Helmholtz-Zentrum Berlin (HZB) enables wafers with perovskite/silicon tandem solar cells to be produced in a vacuum; sufficiently large to replicate industrial production. This globally unique plant helps to develop new close-to-industry processes, materials and solar cells.
