Wet-Chemical Processing of CdS and Alternative Buffer Layers for Cu2ZnSn(S,Se)4 Solar Cells . — •Lwitiko Mwakyusa1, Markus Neuwirth1, Niklas Mathes1, Mario Lang1, Thomas Schnabel2, Erik Ahlswede2, Michael Powalla2,3, Bryce Richards3,4, Heinz Kalt1, and Michael Hetterich11Institute of Applied Physics, Karlsruhe Institute of Technology (KIT), 76131 Karlsruhe, Germany — 2Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (ZSW), 70565 Stuttgart, Germany — 3Light Technology Institute, Karlsruhe Institute of Technology (KIT), 76131 Karlsruhe, Germany — 4Institute of Microstructure Technology, Karlsruhe Institute of Technology (KIT), 76344 Karlsruhe, Germany

Solar cells based on Cu2ZnSn(S,Se)4 (CZTSSe) are promising since they only comprise environmentally friendly and earth-abundant elements. However, their device architecture which has been adopted from Cu(In,Ga)Se2 (CIGS) is not yet optimal. This holds in particular for the CdS buffer. In this contribution we study the fabrication of alternative buffer layers, especially that of (Cd,Zn)S and their impact on the performance of CZTSSe solar cells.
