The Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) in Stuttgart, Germany has set a new world record for a CIGS thin-film solar cell. ZSW scientists succeeded in creating a CIGS cell with a conversion efficiency of 21.7%.
The record-setting cell has an area of 0.5 cm² and was manufactured in a laboratory coating plant by way of a coevaporation process that is highly reproducible in the lab: The scientists made more than 40 cells with efficiency ratings topping the 21% mark. ZSW states that this would indicate that the method lends itself to industrial manufacturing and that it could be readily scaled up to mass production. The Fraunhofer Institute for Solar Energy Systems ISE confirmed the results.
