Hydrazine coordinated Cu chalcogenide complexes and methods for producing the same, the light-absorbing layer coating solution, as well as the manufacturing method of the optical absorption layer coating solution

摘要

And Cu or Cu 2 _Se and a chalcogen, the presence of hydrazine, was reacted with dimethyl sulfoxide does not contain an amine-based solvent, hydrazine is obtained by the resulting solution to adding a poor solvent or concentration and filtration coordinated Cu chalcogenide complexes.
