Abstract

A photoelectric conversion device is composed of a first electrode and a second electrode, at least one of the electrodes being transparent; and a first organic material layer and a second organic material layer, which are overlaid between the first electrode and the second electrode in such a junction relationship that the first organic material layer and the second organic material layer constitute a rectifying junction, the first electrode and the first organic material layer constitute an ohmic junction, and when the first electrode comes into contact with the second organic material layer, the first electrode and the second organic material layer constitutes a rectifying junction, and the second electrode and the second organic material layer constitute an ohmic junction, and when the second electrode comes into contact with the first organic material layer, the second electrode and the first organic material layer constitute a rectifying junction. This photoelectric conversion device may further include an inorganic semiconductor layer between the first or second electrode and the first or second organic material layer when the inorganic semiconductor layer has the same junci…
