ABSTRACT:
The present invention relates to an organic semiconductor device based on phthalocyanine. According to the invention, the device comprises a substrate constituted by a layer (10) of a conductive material covered by a layer (20) of a dielectric material, and a coating deposited on the layer of dielectric material and comprising an extrinsic molecular semiconductor (30) constituted by a monophthalocyanine of a divalent metal or by a hydrogenated monophthalocyanine, and an intrinsic molecular semiconductor (40) constituted by a phthalocyanine giving rise to free radicals.
