  • Abstract
    The influence of Na on structural properties of Cu(In,Ga)Se2 thin films on polyimide(PI) substrate by low temperature 3-stage coevaporation process is investigated. The interdiffusion of In and Ga is hindered in the presence of Na and lead to a decrease of grain size of CIGS near the substrate. Double-peak reflections are found in XRD data of CIGS thin films on substrates with Na. GIXRD data is used and shows a decrease of Ga-incorporation with depth. The problem above can be partly solved by reducing Ga/In ratio. Cross-section SEM micrograph of CIGS films grown with Na shows a smaller grain size near the substrate.
