A method for manufacturing a photoelectric conversion device, that includes: forming a laminate structure of a substrate, a transparent electrode, an active layer produced by wet-coating, and a counter electrode, stacked in this order; and thereafter forming a cavity by: (a) pressing an adhesive material just against a defect formed on the surface of said counter electrode, and then peeling off said adhesive material together with said defect and the peripheral part thereof; or (b) sucking a defect formed on the surface of said counter electrode, so as to remove said defect and the peripheral part thereof, where said cavity penetrates through the counter electrode and unreached to the transparent electrode.

The present embodiments provide a photoelectric conversion device having a laminate structure of a substrate, a transparent electrode, an active layer, and a counter electrode, stacked in this order. In the device, a cavity is provided on the counter electrode-side. The cavity penetrates through the counter electrode and has an opening area larger in the counter electrode than in the active layer.
