A group of researchers from Helmholtz-Zentrum Berlin (HZB) has achieved a new world efficiency record for a silicon-perovskite tandem solar cell, with a certified efficiency of 32.5%.
The current world record of tandem solar cells consisting of a silicon bottom cell and a perovskite top cell is once again at HZB. The new tandem solar cell converts 32.5 % of the incident solar r .
Once again, HZB maintains the world record for tandem solar cells, which combine a silicon bottom cell with a perovskite top cell. A total of 32.5% of the incident solar radiation is converted into electrical energy by the new tandem solar cell.
