Organic photodiode provided with an active zone comprising means for promoting charge carrier collection and conduction

A diode comprising:

• an active zone located between a first electrode and a second electrode, the active zone being formed from at least one semiconducting material, the active zone further comprising one or more conducting or semiconducting elements formed from elongated conducting zones that extend between the electrodes in the material of the active zone along a direction forming a non-zero angle with the electrodes, the elements not being connected to the electrodes and among the elements, one or more first elements is based on a first material promoting conduction of holes, and one or more second elements is based on a second material promoting conduction of electrons,
• the first material and the second material being based on a material different from the material in the regions of the active zone in which the first elements and the second elements are in contact, the first material having a hole conductivity higher than a hole conductivity of the material in the active zone, and the second material promoting conduction of electrons having a conductivity higher than an electron conductivity of the material in the active zone.
