| abstract |
The present invention provides a p-type organic semiconductor material that is easy to manufacture and has high planarity in a polymer skeleton, and has a high photoelectric conversion efficiency using the p-type organic semiconductor material. A material, a photoelectric conversion layer, a photoelectric conversion element, and an organic thin film solar cell are provided. Specifically, a bibenzo [b] furan compound having at least one structural unit represented by the following formula (1) or (2), a photoelectric conversion material using the compound as a p-type organic semiconductor material, and photoelectric conversion Provided are a layer, a photoelectric conversion element, and an organic thin film solar cell. (In the formula, R 13 and R 14 are a hydrogen atom, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, an optionally substituted hydrocarbon group, an optionally substituted hydrocarbon oxy group or a substituted atom. Represents an optionally substituted heterocyclic group.) |
