tandem cell efficiency

Mass-Production all set 28.7% efficient solar cell fabricated in Germany
The record was set by energy solutions supplier Q CELLS as well as German research centre Helmholtz-Zentrum Berlin. The 28.7% effectiveness was accomplished for a 2-terminal tandem solar cell combining a mass-production all set silicon bottom cell based on Q.ANTUM modern technology as well as a top-cell based upon perovskite innovation.
