Abstract: An imaging device comprises at least one unit pixel cell. Each of them comprises: a photoelectric conversion layer having a first and second surfaces; a pixel electrode and a shield electrode located on the first surface and separated from each other, a shield voltage being applied to the shield electrode; an upper electrode located on the second surface and opposing to the pixel electrode and the shield electrode, a counter voltage being applied to the upper electrode; a charge accumulation node electrically connected to the pixel electrode; and a charge detection circuit electrically connected to the charge accumulation node. An absolute value of a difference between the shield voltage and the counter voltage is larger than an absolute value of a difference between the counter voltage and a voltage of the pixel electrode.

Abstract: An imaging device includes a pixel comprising a photoelectric conversion layer having a first surface and a second surface opposite to the first surface; a pixel electrode on the first surface; an auxiliary electrode on the first surface, the auxiliary electrode being spaced from the pixel electrode; an upper electrode on the second surface, the upper electrode facing the pixel electrode and the auxiliary electrode; and an amplification transistor having a gate coupled to the pixel electrode. The imaging device also includes voltage application circuitry that generates a first voltage and a second voltage different from the first voltage, the voltage application circuitry being coupled to the auxiliary electrode. The voltage application circuitry selectively supplies either the first voltage or the second voltage to the auxiliary electrode.
