CIGS thin-film solar cells — •Stefan Paetel — Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden Württemberg (ZSW), Industriestraße 6, 70565 Stuttgart, Germany

This talk covers the current status and understanding of high-efficiency Cu(In,Ga)Se₂ solar cells. Starting with the principal setup of these cells the various parts of the multilayer system will be introduced: substrate, back-contact, absorber, buffer and front contact. This includes the structural, optical and electronic properties of the materials. Furthermore relevant deposition methods are presented along with module manufacturing issues.
