The present specification discloses that the dissolution of a chalcogenide element in a non-explosive hydrazine solvent is possible by adding sodium to the non-explosive hydrazine solvent. Accordingly, in the disclosure, the dissolution of a metal chalcogenide compound through a dimension reduction mechanism was possible even if the non-explosive hydrazine solvent was used. Therefore, in the disclosure, provided is a precursor solution for forming a chalcogenide film containing the non-explosive hydrazine solvent which is less poisonous than hydrazine and has no explosiveness as a solvent. |
