13 - 229Microroughness and Composition of Cyanide-Treated CuInS2. —The effect of KCN etching on morphology and stoichiometry of polycrystallineand single crystalline CuInS2 surfaces is investigated using atomic force mi-croscopy. While single crystalline samples are strongly attacked by the KCNsolution, polycrystalline CuInS2 is subjected to roughening only after prolongedetching treatment. As revealed by XPS the etching process results in an In-richcomposition of the surface. The chemical reactions leading to CuS and CuInS2
dissolution are discussed. — (WEBER, M.; SCHEER, R.; LEWERENZ, H.J.; JUNGBLUT, H.; STOERKEL, U.; J. Electrochem. Soc. 149 (2002) 1,G77-G84; Abt. Sol. Energ., Hahn-Meitner-Inst., D-14109 Berlin, Germany;EN)
