Abstract

The invention discloses an inverted organic light-emitting device and a preparation method thereof. The inverted organic light-emitting device comprises a semiconductor transparent conductive film, analuminum layer, an organic layer and a metal electrode, wherein the semiconductor transparent conductive film is a substrate layer, the aluminum layer is arranged between the semiconductor transparent conductive film and the organic layer, and the metal electrode covers the upper surface of the organic layer to form the inverted organic electroluminescent device. Through the inverted organic light-emitting device and the preparation method thereof provided by the invention, the current efficiency of the organic light-emitting device can be improved.

Description

Technical field [0001] The present invention relates to the field of organic electroluminescence devices, in particular to an inverted organic electroluminescence device and a preparation method thereof. Background technique [0002] In recent years, organic electroluminescent devices have been widely used in actual production and life, especially in the field of lighting display. Compared with traditional inorganic electroluminescent devices, their research, preparation and application have become the most advanced One of the active research fields. [0003] Organic electronic devices are semiconductor devices with specific functions prepared on the basis of organic materials that can conduct electricity. Since most of the organic materials in organic electronic devices are composed of carbon and hydrogen, using them as electronic devices has many advantages, such as Easy to make, low cost, chemically adjustable, transparent and flexible, etc. We can use these advantages of orga...
