Abstract: Atomic-scale structural parameters of Cu(In,Ga)Se2 powders and polycrystalline thin filmswere determined as afunction of the In and Cu contents using X-ray absorption spectroscopy. No difference in the two sample types isobserved for the average bond lengths demonstrating the strong tendency towards bond length conservationtypical for tetrahedrally coordinated semiconductors. In contrast, the bond length variation is significantly smallerin the thin films than in the powders, particularly for Cu-poor material. This difference in the nanostructure isproposed to originate fromdifferences in the preparation conditions,most prominently fromthe different historyof Cu composition.
