Perovskites move into production

Perovskites remain a great hope for the future of the solar industry, once the possibilities of tunnel oxide passivated contact (TOPCon) and heterojunction PV have been exhausted. A look at the latest perovskite research shows that industry optimism is built on a strong foundation.

 World records for perovskite solar cells have a short shelf life. Until April 2022, a silicon-perovskite tandem cell from Helmholtz-Zentrum Berlin (HZB), a German research organization, led with an efficiency of 32.5%. Researchers at the Photovoltaics Laboratory of the King Abdullah University of Science and Technology (KAUST), in Saudi Arabia, later hit 33.2%, and then …
