Atom probe study of sodium distribution in polycrystalline Cu(In,Ga)Se2 thin film / E. Cadel in Acta materialia, Vol. 58 N° 7 (Avril 2010)  

Public ISBD [article]  inActa materialia > Vol. 58 N° 7 (Avril 2010) . - pp. 2634–2637 Titre : Atom probe study of sodium distribution in polycrystalline Cu(In,Ga)Se2 thin film Type de document : texte imprimé Auteurs : E. Cadel, Auteur ; N. Barreau, Auteur ; J. Kessler, Auteur Année de publication : 2011 Article en page(s) : pp. 2634–2637 Note générale : Métallurgie Langues : Anglais (eng) Mots-clés : Thin film solar cell Atom probe Sodium Grain boundary Résumé : This article reports the first investigations of CuIn1−xGaxSe2 (CIGSe) polycrystalline thin films by means of atom probe tomography. Attention is focused on the distribution of Na atoms within the films. Both Na-containing and Na-free CIGSe thin films have been investigated. When Na is available during the CIGSe coevaporation, it is observed to be mainly segregated at the grain boundaries of the films; however, it is also detected within the grains of CIGSe at very low concentration.
