Abstract
A photoelectric conversion device including a first electrode, a second electrode. a photoelectric conversion layer, a first electric charge block layer, and a second electric charge block layer is provided. The second electrode faces the first electrode. The photoelectric conversion layer is between the first electrode and the second electrode. The first electric charge block layer is between the first electrode and the photoelectric conversion layer. The first electric charge block layer includes an organic material having an HOMO level that is deeper by 1 eV or higher and an LUMO level ranging from 3.7 eV to 4.8 eV inclusive, with respect to a work function of the first electrode. The second electric charge block layer is between the first electric charge block layer and the photoelectric conversion layer. Each of the photoelectric conversion layer and the second electric charge block layer include fullerenes or fullerene derivatives.
