Abstract:
The invention relates to an organic light-emitting component (100), comprising a functional layer stack (9) between two electrodes (1, 8), wherein the functional layer stack (9) has at least two organic light-emitting layers (2, 7) and at least one charge carrier generation zone (3), which is arranged between the two organic light-emitting layers (2, 7), wherein the charge carrier generation zone (3) comprises an electron-conducting organic layer (31) and a hole-conducting organic layer (32), between which an intermediate region (4) is arranged, wherein the intermediate region (4) comprises at least one organic intermediate layer (6) which has a first charge carrier transport mechanism and an inorganic intermediate layer (5) which has a second charge carrier transport mechanism, wherein the inorganic intermediate layer (5) is arranged between the organic intermediate layer (6) and the electron-conducting organic layer (31), and wherein the first charge carrier transport mechanism is at least partially different to the second charge carrier transport mechanism.
