Switzerland researchers build perovskite-silicon solar cells that break 30 percent efficiency barrier

For the first time, researchers from the École polytechnique fédérale de Lausanne (EPFL) and CSEM in Switzerland have broken the efficiency record for tandem silicon-perovskite solar cells, surpassing the 30% mark. The new record pushes the technology beyond the limits of silicon by utilizing low-cost and scalable materials. The EPFL PV-lab team in Neuchâtel (Dr. […]
