Abstract: An imaging device includes: a first pixel array including a first photoelectric converter and first pixel electrodes connected to the first photoelectric converter; and a second pixel array including a second photoelectric converter and second pixel electrodes connected to the second photoelectric converter. The first pixel array and the second pixel array are stacked one on another. In a plan view, an area of an overlapping region defined by overlapping between the first pixel electrodes and a corresponding second pixel electrode of the second pixel electrodes is smaller than an area of a remaining region obtained by excluding the overlapping region from the corresponding second pixel electrode.

Abstract: A photoelectric converter includes a support face, and a photoelectric conversion film. The photoelectric conversion film is disposed at the support face. In a first cross-section parallel to a perpendicular direction that is perpendicular to the support face, the photoelectric conversion film has a first sloped face. In the first cross-section, the inclination angle of the first sloped face relative to a first parallel direction, which is parallel to the support face, is defined as a first slope angle. The first slope angle is greater than 0° and less than or equal to 5°.

Abstract: An imaging device includes a photoelectric conversion layer, a counter electrode provided above the photoelectric conversion layer, a pixel electrode that faces the counter electrode with the photoelectric conversion layer disposed between the counter electrode and the pixel electrode, and a contact plug covered with the pixel electrode and connected to the pixel electrode. The pixel electrode includes a first layer and a second layer provided on the first layer in contact with the first layer. A surface of the first layer that is in contact with the second layer has a protrusion that protrudes upward.

Abstract: An image sensor includes a photoelectric conversion film, an upper electrode, and a connector. The upper electrode is located on or above the photoelectric conversion film. The connector is electrically connected to the upper electrode. On a first section parallel to a direction perpendicular to the photoelectric conversion film, the connector is in contact with the side surface of the photoelectric conversion film. On the first section, the upper electrode extends to a position outward of the outer edge of the upper surface of the photoelectric conversion film.

Abstract: An imaging device includes a pixel electrode, a counter electrode facing the pixel electrode, and a photoelectric conversion layer located between the pixel electrode and the counter electrode. The counter electrode includes a first transparent electrode, a second transparent electrode, and an intermediate layer located between the first transparent electrode and the second transparent electrode. A material of the intermediate layer is different from a material of the first transparent electrode and different from a material of the second transparent electrode. The photoelectric conversion layer, the first transparent electrode, the intermediate layer, and the second transparent electrode are arranged in this order. The intermediate layer contains an insulating material as a major ingredient.
