Abstract
An imaging device includes a pixel electrode, a counter electrode that faces the pixel electrode, a first photoelectric conversion layer that is located between the pixel electrode and the counter electrode and that generates first signal charge, a second photoelectric conversion layer that is located between the first photoelectric conversion layer and the pixel electrode and that generates second signal charge, a first barrier layer that is located between the first photoelectric conversion layer and the second photoelectric conversion layer and that forms a first heterojunction barrier against the first signal charge in the first photoelectric conversion layer, and a charge accumulator that is electrically connected to the pixel electrode and that accumulates the first signal charge and the second signal charge.
