Abstract
A photoelectric conversion element according to an embodiment includes: a first electrode; a second electrode; and a photoelectric conversion layer that is in contact with the first electrode and the second electrode and includes an active layer containing a perovskite compound. The active layer gives an X-ray diffraction pattern having a first diffraction peak ascribed to the (004) plane of the perovskite compound and a second diffraction peak ascribed to the (220) plane of the perovskite compound. The ratio of the maximum intensity of the first diffraction peak to the maximum intensity of the second diffraction peak is 0.18 or more.
