Dye-sensitized photoelectric conversion element

A dye-sensitized photoelectric conversion element comprising:

• at least one dye-sensitized photoelectric conversion cell, wherein
• the dye-sensitized photoelectric conversion cell includes:
• a first electrode;
• a second electrode facing the first electrode;
• an oxide semiconductor layer provided on the first electrode;
• and
• an electrolyte provided between the first electrode and the second electrode, wherein the second electrode includes:
• an annular portion;
• an approaching portion approaching the oxide semiconductor layer closer than the annular portion;
• and
• an annular connecting portion connecting the annular portion and the approaching portion, and
• the oxide semiconductor layer includes:
• an inner part facing the approaching portion of the second electrode on the first electrode;
• and
• an annular outer part that is provided around the inner part and faces the connecting portion of the second electrode, wherein
• the outer part includes:
• a plurality of linear portions separated from one another and a corner portion connecting two adjacent linear portions to each other among the plurality of linear portions in a case in which the outer part is viewed in a thickness direction of the oxide semiconductor layer,
• a thickness of the corner portion of the outer part is greater than a thickness of the linear portion of the outer part, and
• a thickness of the linear portion of the outer part is greater than a thickness of the inner part.
