CIGS-Pero tandem solar cells: Research team sets new world record

By | February 5, 2025

By combining two semiconductor thin films into a tandem solar cell, high efficiencies can be achieved with a minimal ecological footprint. Teams from the Helmholtz-Zentrum Berlin (HZB) and Humboldt University of Berlin have now presented a tandem cell made of CIGS and perovskite that holds a new world record with an efficiency of 24,6%. This value was determined by the Fraunhofer Institute for Solar Energy Systems ISE… Read more »
