Abstract

Provided are a photoelectric conversion element and a photoelectric conversion apparatus each having improved conversion efficiency. The photoelectric conversion element includes first and second electrodes, and a photoelectric conversion layer containing a crystal having a perovskite structure, and is characterized in that: the photoelectric conversion element includes, between the photoelectric conversion layer and the first electrode, a charge-transporting layer containing a crystal of a cyclic conjugated compound in which a plurality of pyrrole rings are bonded by conjugated bonds; in a scanning range of a Bragg angle 20 in an X-ray diffraction spectrum of the charge-transporting layer using a CuKα ray, when a peak with the maximum intensity out of peaks that are present in a range of 5.0 to 8.0° is defined as a peak α and a peak with a maximum intensity out of peaks that are present in a range of 26.0 to 29.0° is defined as a peak β, one of the peak α or the peak β is a peak with the maximum intensity in the scanning range; and when the intensity of the peak α is defined as Iα and the intensity of the peak β is defined as Iβ, a ratio Iα/Iβ is 2.0 or less.
