Abstract: Provided are: a composite polymer semiconductor having a mesh shape formed by mixing a conjugated polymer and an insulating polymer; and a method for producing same. A composite polymer having a mesh structure is produced by introducing a small quantity of a conjugated polymer to an insulating polymer. The produced composite polymer having a mesh structure increases charge mobility, minimizes visible light absorption through the introduction of the small quantity of the conjugated polymer, and thus can be used as a transparent and flexible organic electronic element.

Abstract: Disclosed is a method for manufacturing an inverted organic electronic device. The method includes preparing a substrate having a first electrode; depositing a mixture of a cathode interface material and a photo active material onto the first electrode to form a bilayer or composite layer of a cathode interface layer and a photo active layer, followed by forming an anode interface layer on the bilayer or composite layer; and forming a second electrode on the anode interface layer. According to the present invention, it is possible to achieve simplification of a manufacturing process of an inverted organic electronic device and to provide an inverted organic electronic device having excellent performance by forming a cathode interface layer in the form of a uniform and pinhole-free thin film.
