<p>The diode according to the invention comprises at least one organic layer made of bipolar material for blocking either electrons on the anode side, or holes, on the cathode side. According to the invention, the charge-blocking function is therefore provided no longer by a potential barrier effect but by a difference in intrinsic mobility of the charges within the bipolar organic material. Thanks to the use of this type of material for the blocking layer, the lifetime of the diodes is substantially improved.</p> |
