  • Patent number: 10005879
    Abstract: A method for producing an organic semiconductor device (110) having at least one organic semiconducting material (122) and at least two electrodes (114) adapted to support an electric charge carrier transport through the organic semiconducting material (122) is disclosed. The organic semiconducting material (122) intrinsically has ambipolar semiconducting properties. The method comprises at least one step of generating at least one intermediate layer (120) which at least partially is interposed between the organic semiconducting material (122) and at least one of the electrodes (114) of the organic semiconductor device (110). The intermediate layer (120) comprises at least one thiol compound having the general formula HS—R, wherein R is an organic residue. The thiol compound has an electric dipole moment pointing away from the SH-group of the thiol compound. The electric dipole moment has at least the same magnitude as the electric dipole moment in 4-Phenylthiophenol.
