Such a high performance is currently only attainable by the incorporation of heavy alkali metals like Cs into the absorber through an alkali fluoride post-deposition treatment (PDT). As the effect of the incorporated heavy alkali metals is under discussion, we investigated the local composition and microstructure of high efficiency CIGS solar cells via various high-resolution techniques in a combinatory approach. An accumulation of Cs is clearly detected at the p-n junction along with variations in the local CIGS composition, showing the formation of a beneficial secondary phase with a laterally inhomogeneous distribution. Additionally, Cs accumulations were detected at grain boundaries with a random misorientation of the adjacent grains where a reduced Cu concentration and increased In and Se concentrations are detected. No accumulation was found at Σ3 twin boundaries as well as the grain interior. These experimental findings are in excellent agreement with complementary ab-initio calculations, demonstrating that the grain boundaries are passivated by the presence of Cs. Further, it is unlikely that Cs with its large ionic radius is incorporated into the CIGS grains where it would cause detrimental defects. author: - first_name: Philipp full_name: Schöppe, Philipp last_name: Schöppe - first_name: Sven full_name: Schönherr, Sven last_name: Schönherr - first_name: Manjusha full_name: Chugh, Manjusha id: '71511' last_name: Chugh - first_name: Hossein full_name: Mirhosseini, Hossein id: '71051' last_name: Mirhosseini orcid: https://orcid.org/0000-0001-6179-1545 - first_name: Philip full_name: Jackson, Philip last_name: Jackson - first_name: Roland full_name: Wuerz, Roland last_name: Wuerz - first_name: Maurizio full_name: Ritzer, Maurizio last_name: Ritzer - first_name: Andreas full_name: Johannes, Andreas last_name: Johannes - first_name: Gema full_name: Martínez-Criado, Gema last_name: Martínez-Criado - first_name: Wolfgang full_name: Wisniewski, Wolfgang last_name: Wisniewski - first_name: Torsten full_name: Schwarz, Torsten last_name: Schwarz - first_name: Christian full_name: T.
