Method of producing such substances in a vacuum using a post-chalcogenide techniques and chalcogenide-based material

摘要

The present invention provides a strategy for producing a CIGS light absorbing composition of the high-quality substrate (18) on the precursor (s) film was sputtered from (112). This precursor is S and "post-selenide" and / or when Se is used, for example (chalcogenides process using a technique capable of pressure under exceptionally low, to cause post-chalcogen treatment and by) are referenced, including when used in a "post-sulfide" as "post-chalcogenide" is converted into the CIGS absorber. Therefore, the strategy of the present invention, a continuous process, for example, easily incorporated into in a roll-to-roll process or batchwise process takes place under vacuum. The present invention is useful laboratory, on an industrial scale and pilot plant. (114), for example, is capped by elemental chalcogen second layer, which is then heat treated using the evaporation, the precursor film (112) to form chalcogenide layer (20).
