| Résumé |
|
Atom probe tomography (APT) has been used to study the distribution of Na atoms in polycrystalline Cu(In,Ga)Se-2 (CIGSe) thin films. APT, which allows separate investigations of grain boundaries and grain interiors chemistry, shows the presence of inter- and intra-granular Na segregations. It is highlighted that these segregations are found associated to Cu-depletion and In-enrichment. The segregation of Na to crystalline point defects and extended ones is finally discussed regarding its impact on the electrical properties of CIGSe layers. (C) 2015 Acta Materialia Inc.
