Problems solved by technology

Chun YG et al. (7) Further, this method is used to synthesize elements copper, indium, gallium, and selenium to obtain CIGS powder. Only this method cannot be mass-produced due to limited reaction conditions.
[0014] Looking at the above technical solutions, some can only produce ternary compounds, some require high temperature and high pressure synthesis conditions and are not suitable for mass production, and some products contain halogen ions, which cannot meet the production and component requirements.

Abstract

The invention relates to preparation methods of a multi-element metal chalcogen compound, a target and a coating material. The preparation method of the multi-element metal chalcogen compound comprises the following steps of: synthesizing an elementary substance powder selected from forming elements at normal pressure with a liquid phase synthesis method, wherein the used organic solvent in the synthesis process is an aromatic amines compound with a boiling point higher than 240 DEG C and pH value of 7-10, and thereby producing a copper-indium-gallium-selenium element compound through chelation reactions at high temperature. The compound can be particularly applied to the solar energy field of semiconductor films, can be directly coated into a film and sputtered to a film through producing a target, the selenylation process is unneeded, the production procedure can be reduced, the consistency of the film components is improved, and the product yield and the efficiency are enhanced.
