Combining two semiconductor thin films into a tandem solar cell can achieve high efficiencies with a minimal environmental footprint. Teams from HZB and Humboldt University Berlin have now presented a CIGS-perovskite tandem cell that sets a new world record with an efficiency of 24.6%, certified by the independent Fraunhofer Institute for Solar Energy Systems.
Helmholtz-Zentrum Berlin (HZB), in collaboration with Humboldt University Berlin, has achieved a new world record for the efficiency of CIGS-perovskite tandem solar cells. The record-breaking efficiency of 24.6% has been certified by the independent Fraunhofer Institute for Solar Energy Systems. This innovative tandem cell combines a CIGS bottom cell with a perovskite top cell, leveraging advancements in contact layers between the cells. This breakthrough is a significant milestone in solar technology, promising highly efficient solar cells with a reduced environmental impact.
