ABSTRACT:
A photoelectric converter comprising a photoelectric conversion unit which includes a pair of main electrodes, spaced by a photoreception area over a semiconductor layer, and an auxiliary electrode. The semiconductor layer and the auxiliary electrode are laminated through the intermediary of an insulating layer in at least the photoreception area. It also includes a storage capacitor for storing electric charges flowing through the photoelectric conversion unit, a transfer transistor for transferring the charges stored in the capacitor, a discharge transistor for discharging the charges stored in the storage capacitor, and dividing device for dividing a switching voltage applied to the control electrode of the discharge transistor to apply a divided voltage to the auxiliary electrode.
