Abstract
A photoelectric conversion element including a thin film composed of a transition metal dichalcogenide and formed on a base material. In the present invention, a surface of the thin film composed of the transition metal dichalcogenide is modified with at least any nanorod particles of Au nanorod particles composed of Au and Ag nanorod particles composed of Ag. An average aspect ratio of the Au nanorod particles is 3.0 or more and 12.0 or less, and an average aspect ratio of the Ag nanorod particles is 3.0 or more and 13.0 or less. In the invention, the sensitivity to light having wavelengths in the near-infrared region improves by a sensitizing action attributed to localized surface plasmon resonance that is developed by the Au and Ag nanorod particles.
