Large-area perovskite solar module with 18% efficiency
Researchers in Germany claim to have overcome the main challenge for the development of large-area perovskite PV modules - scaling up from the cell to the module level. They achieved an efficiency of up to 16.6% on a module surface of ??more than 50 centimeters squared, and 18% on a module with an area of 4 centimeters squared.Scientists at Germany s Karlsruhe Institute of Technology (KIT) claim to have achieved an efficiency of 18% for a perovskite solar module with an area of ??4cm2 - a world record for a vacuum-processed perovskite panel. The researchers explained they were able to scale up .
