Fraunhofer team develops promising perovskite-based triple-junction solar cell
A research team at the Fraunhofer Institute for Solar Energy Systems ISE has reported a perovskite/perovskite/silicon triple-junction solar cell with an open circuit voltage of >2.8 V, which is said to be the record value reported for this structure so far. The Fraunhofer team showed that perovskite-perovskite-silicon subcells can hold considerable promise and have an even greater efficiency potential than double-junction tandem cells.
The triple-junction solar cell was developed as part of the Triumph research project funded by the European Commission and the RIESEN research project funded by the German Federal Ministry for Economic Affairs and Climate Action. This achievement confirms that the cell has excellent material properties for generating electricity, leading the scientists to deduce that it has an efficient solar cell architecture.
