FORMATION OF SELENIDE, SULFIDE OR MIXED SELENIDE-SULFIDE FILMS ON METAL OR METAL COATED SUBSTRATES

摘要

A process and composition for preventing cracking in composite structures comprising a metal coated substrate and a selenide, sulfide or mixed selenide­sulfide film. Specifically, cracking is prevented in the coating of molybdenum coated substrates upon which a copper, indium-gallium diselenide (CIGS) film is deposited. Cracking is inhibited by adding a Se passivating amount of oxygen to the Mo and limiting the amount of Se deposited on the Mo coating.
