Q CELLS along with Helmholtz-Zentrum Berlin achieved a new world record efficiency for a 2-terminal tandem solar cell that combines a mass-production ready silicon bottom cell based on Q.ANTUM technology and a top-cell based on perovskite technology. An efficiency of 28.7% was achieved.
The joint achievement from Q CELLS and Helmholtz-Zentrum Berlin sets a new world record for 2-terminal tandem solar cell efficiency based on perovskite top-cell technology and using a mass-production-ready silicon bottom cell based on Q.ANTUM technology.
