  • Multi-layer compound precursor with CuSe thermal conversion to Cu2-xSe for two-stage CIGS solar cell absorber synthesis
    Publication number: 20140366946
    Abstract: Fabricating a layered precursor includes depositing a first film including a first indium gallium selenide compound on a substrate; then depositing a second film including a first CuSe compound; then heating the substrate, the first film and the second film to convert the first CuSe compound in the second film to a first Cu2-xSe (0=<x<1) compound; and then depositing a third film including a indium gallium selenide compound. A layered precursor includes a substrate; a first film coupled to the substrate, the first film including a first indium gallium selenide compound; a second film coupled to the first film, the second film including a first Cu2-xSe where (0=<x<=1) compound; and a third film coupled to the second film, the third film including a second indium gallium selenide compound.
