Karlsruher Institut für Technologie (KIT) researchers have now produced perovskite/CIS tandem solar cells with an efficiency of nearly 25 percent – the highest value achieved thus far with this technology. In addition the new combination of materials is light and versatile, making it possible to envision the use of these tandem solar cells in vehicles, […]

Ecole Polytechnique Fédérale de Lausanne (EPFL) researchers have combined silicon and perovskite materials making a tandem solar cell. The resulting efficiency of 25.2 percent is a record for this type of tandem cell. Their innovative yet simple manufacturing technique could be directly integrated into existing production lines, and efficiency could eventually rise above 30 percent. […]
