摘要：
The present invention aims to provide an ink for an active layer of an organic solar cell, wherein an active layer having high energy conversion efficiency can be stably and easily formed from the ink; an organic solar cell having high energy conversion efficiency; and a method for producing the organic solar cell. A first aspect of the present invention is an ink for an active layer of an organic solar cell, the ink comprising: an organic semiconductor compound; an inorganic semiconductor compound; an organic solvent; and a dispersant; wherein the dispersant is a compound having a structure with an aromatic ring and/or heterocyclic ring and a polar group asymmetrically bonded to the structure, and fulfills all of the following requirements (1) to (3): (1) the dispersant has a lower LUMO level than the organic semiconductor compound; (2) solubility of the dispersant in the organic solvent is equal to or higher than solubility of the organic semiconductor compound in the organic solvent; and (3) the dispersant has a higher HOMO level than the inorganic semiconductor compound.
