A process and composition for preventing cracking in composite structures comprising a metal coated substrate and a selenide, sulfide or mixed selenide sulfide 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.

Formation of selenide, sulfide or mixed selenide-sulfide films on metal or metal coated substrates

A multiple nozzle thermal evaporation source includes a plurality of nozzles having a tapered shape. The nozzles may comprise a thermally conductive material having a low emissivity material.

Multiple-nozzle thermal evaporation source

Thin films are produced by a method wherein a material is heated in a furnace placed inside a vacuum system. An inert gas is flown over/through the heated material. The vapors of the material are entrained in the carrier gas which is then directed onto a substrate heated to a temperature below that of the furnace temperature and placed in close proximity to the exit of the furnace.
