Teams from the Helmholtz-Zentrum Berlin and École Polytechnique Fédérale de Lausanne, Switzerland, have been the first to successfully combine a silicon heterojunction solar cell with a perovskite solar cell monolithically into a tandem device. The hybrid tandem cell showed an efficiency of 18 percent. That is the highest currently reported value for this type of device architecture. There are even prospects for the efficiency to reach as much as 30 percent.
