Abstract: A photoelectric conversion apparatus includes: a pair of electrodes including a first electrode and a second electrode; a charge separator disposed to make contact with the first electrode; an insulative polarizer disposed to intervene between the charge separator and the second electrode; and an incidence switcher alternately switching between an incident state where a light falls on the charge separator, and a non-incident state where the light does not fall on the charge separator, based on an electromotive force arising between the first electrode and the second electrode. The charge separator separating the charge, the insulative polarizer storing and discharging the separated charge, and the incidence switcher switching between the incident state and the non-incident state make the photoelectric conversion apparatus self-oscillate to sustainably output an alternating current or alternating voltage from the output terminals.
