The reaction of metallic precursors has become the primary method of industrial manufacturing for Cu(In,Ga)Se2. Commonly used Cu3Ga sputter targets have thus far dictated that the relative Ga composition of these precursors is Ga/(In+Ga) [Formula: se

CIGS absorbers are developed using Se-capped precursor films with increased Ga composition. Films are reacted using a rapid thermal process, which uses reaction times on the order of minutes. It is observed that Ga profiles can be controlled by adjus

Cu(In,Ga)(Se,S)2 (CIGSS) absorbers with thicknesses from 1.9 to 0.25 μm have been grown using a three-step selenization/Ar-anneal/sulfization reaction of Cu-In-Ga metal precursors. Material characterization revealed changes in orientation, apparent

A detailed structural analysis of the (AgCu)(InGa)Se 2 thin film alloy system was undertaken via X-ray diffraction in order to determine its phase behavior and the chalcopyrite phase lattice constants of the alloy system. Thin films were grown by ele

The compositional distribution of Ga and S in Cu(InGa)(SeS) 2 films fabricated by a simultaneous selenization and sulfization process was systematically investigated. At low H 2 Se/H 2 S reaction temperature (490 °C), most Ga remains at the back of
