Tandem solar cell achieves 32.5% efficiency

The current world record of tandem solar cells consisting of a silicon bottom cell and a perovskite top cell has once again been broken at HZB. The new tandem solar cell converts 32.5% of the incident solar radiation into electrical energy. The certifying institute European Solar Test Installation (ESTI) in Italy measured the tandem cell and officially confirmed this value which is also included in the NREL chart of solar cell technologies, maintained by the National Renewable Energy Lab, U.S..
