Abstract: A chalcogen element can be effectively dissolved in a non-explosive hydrazine-based solvent by the aid of sodium in a non-explosive hydrazine-based solvent. Therefore, a precursor solution for forming a metal chalcogenide film containing as a solvent a non-explosive hydrazine-based solvent which is less poisonous than hydrazine and which is free of explosiveness is provided. A metal chacogenide thin film may be formed employing the metal chalcogenide precursor solution.
