摘要
1st this invention contains the organic-semiconductor compound, the inorganic semiconductor compound, the organic solvent, and the dispersing agent, and the said dispersing agent couple | bonded with the skeleton which has an aromatic ring and / or a heterocyclic ring, and the asymmetrical position of this skeleton. It is a compound having a polar group, and the dispersant is an organic solar cell active layer ink that satisfies all of the following (1) to (3). (1) The LUMO level is lower than the LUMO level of the organic semiconductor compound. (2) The solubility in the organic solvent is the same as or higher than the solubility of the organic semiconductor compound in the organic solvent. (3) The HOMO level is higher than the HOMO level of the inorganic semiconductor compound. 2nd this invention is an organic solar cell which has an active layer in which an inorganic semiconductor compound exists in an organic semiconductor compound, Comprising: In the cut surface of the thickness direction of the said active layer, 20% of film thickness from a cathode side surface It is an organic solar cell whose area ratio of the said inorganic semiconductor compound in the area | region to the thickness of is 75 to 100%.
