    摘要： An organic EL device comprises: a light-transmissive substrate; a transparent electrode; an organic emitting layer; and an opposing electrode. A light-extraction layer provided by layering a high refractive index layer adjoining the transparent electrode and a low refractive index layer adjoining the light-transmissive substrate includes recess-protrusion units each provided by a protrusion and a recess at an interface between the high refractive index layer and the low refractive index layer. In at least one of the recess-protrusion units, a distance from the interface between the high refractive index layer and the low refractive index layer to an interface between the transparent electrode and the high refractive index layer is equal to or more than an optical coherence length and a height of the protrusion, a width of the protrusion and a gap between the protrusion and another protrusion adjoining the protrusion across the recess is 1 μm or more.

    摘要： A photoelectric conversion device including a substrate, a photoelectric conversion element including a first electrode, a second electrode and an organic compound layer and a sealing member that are disposed in this order. When a cross section of the photoelectric conversion device in a thickness direction is observed with the sealing member being placed at an upper side, a bonding member seals the organic compound layer at an outside thereof. An output electrode on the sealing member has a protrusion. A side conductive portion is electrically connected with the protrusion in an up-and-down direction. A substrate conductive member electrically connected with the first electrode and the second electrode extends to an outside of the bonding member. An electrical connecting member electrically connects the side conductive portion to the substrate conductive member at a further outside of the bonding member.
