Abstract:
A photoelectric conversion apparatus comprising:a photoelectric conversion device having a first electrode layer, a second electrode layer, and a semiconductor layer between said first electrode layer and said second electrode layer;first and second switch devices each having first and second main electrodes;first and second power sources;a reading circuit, said first electrode layer being electrically connected to said first main electrode of said first switch device, said second electrode layer being electrically connected to said first power source, said second main electrode of said first switch device being electrically connected to said reading circuit, said first main electrode of said second switch device being electrically connected to said second main electrode of said first switch device and to said reading circuit, and said second main electrode of said second switch device being connected to said second power source; andmeans for outputting a signal for refresh driving by applying an electric field in a direction for guiding carriers from said second power supply to said second electrode layer, and for simultaneously outputting a signal for turning on said first switch device, thereby fixing a potential on a first electrode layer side of said photoelectric conversion device.
