European record: ZSW achieves 10.3% efficiency with Kesterite absorber material
Scientists in Stuttgart had a breakthrough in their search for more advantageous materials and processes in the manufacture of efficient thin-film solar cells. A team of researchers at the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (Centre for Solar Energy and Hydrogen Research Baden-Württemberg, ZSW) has developed a simplified production process for Kesterite thin-film solar cells. The absorber layer of the new cells contains tin and zinc, two readily available and inexpensive materials. The top-performing cell reaches an efficiency of 10.3% – a new European record.
