NOVELTY - Organic electronic or optoelectronic component on a flexible substrate (1), comprises an electrode, a counter electrode, and a layer system which is located between the electrode and the counter electrode, and consists of a layer close to the substrate, made of a non-conductive or poorly conductive material (2), a metallic layer (3) and a conductive or semi-conductive material layer (4), where the metallic layer has a refractive index that is greater than the refractive index of the flexible substrate.    USE - The component is useful for electronic and optoelectronic devices, preferably in solar cells.    ADVANTAGE - The electronic or optoelectronic component: is produced in a simple and cost-efficient manner using cheaper materials; ensures homogeneous function, with short-circuit-free contacting and a homogeneous distribution of the electric field; exhibits high optical absorption coefficient; enables flexible structure and increased light absorption, thus it leads to improved efficiency of the solar cell; and provides improved service life.
