Perovskite progress

In December 2022, Helmholtz-Zentrum Berlin (HZB) set a new efficiency record for a perovskite-silicon tandem cell, at 32.5%. Scientists at the institute continue to investigate the long-term stability improvements and large scale processes needed to make this technology a commercial reality, as pv magazine found out when it caught up with Steve Albrecht, TU Berlin professor and HZB’s head of department for perovskite tandem solar cells, and Antonio Abate, who heads the institute’s department for active materials and interfaces for stable perovskite solar cells.
