    摘要: A photoelectric conversion element of an embodiment includes a first electrode, a second electrode, and a light-absorbing layer containing a chalcopyrite-type compound containing a group Ib element, a group IIIb element, and a group VIb element between the first electrode and the second electrode. A region in which concentration of the group Ib element in the light-absorbing layer is from 0.1 to 10 atom %, both inclusive, is included in a region up to a depth of 10 nm in a direction from a principal plane of the light-absorbing layer on a side of the second electrode to a side of the first electrode.
