Title: PHOTOELECTRIC CONVERSION DEVICE
Abstract:
Disclosed is a photoelectric conversion device provided with: a photoelectric conversion element; a voltage converting unit which boosts a voltage output from the photoelectric conversion element; an electricity storage unit capable of being charged up to a voltage output from the voltage converting unit; a load unit for applying the voltage of the electricity storage unit; a voltage monitoring unit which monitors the voltage of the electricity storage unit; a switch unit which switches between a first state in which the voltage output from the voltage converting unit is applied only to the electricity storage unit, and a second state in which the voltage output from the voltage converting unit is not applied to either the electricity storage unit or the load unit; and a control unit. If the voltage of the electricity storage unit being monitored by the voltage monitoring unit reaches a fully-charged voltage of the electricity storage unit, the control unit performs control such that the switch unit switches to the second state to discharge the electricity storage unit and apply a voltage to the load unit, and if the voltage of the electricity storage unit being monitored by the voltage monitoring unit becomes less than the fully-charged voltage of the electricity storage unit, the control unit performs control such that the switch unit switches to the first state to charge the electricity storage unit. The photoelectric conversion element includes at least one photoelectric conversion cell, wherein the photoelectric conversion cell includes an electrode board, an opposing board which opposes the electrode board, an oxide semiconductor layer provided on the electrode board or the opposing board, a pigment supported in the oxide semiconductor layer, and an electrolyte which is disposed between the electrode board and the opposing board and which contains a redox pair.
