Photodiode device containing a capacitor for controlling dark current or leakage current

An organic photodiode, comprising:

• a first electrode forming an anode;
• a second electrode forming a cathode;
• an active layer provided between the first electrode and the second electrode;
• at least one third electrode, the third electrode being provided in the active layer between the first electrode and the second electrode and being in contact neither with the first electrode nor with the second electrode, the third electrode forming with the first electrode or with the second electrode or with a fourth electronic distinct from the first and the second electrodes, plates of a capacitance to trap at least part of dark current or leakage current of the photodiode;
• and
• means including tracks and/or pads enabling the third electrode and/or the fourth electrode to be powered using a voltage supply means, to apply a voltage across the capacitance, as a function of the dark current or the leakage current.
