Problems solved by technology
[0004] In addition, traditional organic optoelectronic devices also have some problems: traditional organic optoelectronic devices have a single function, which is not conducive to the formation of fully organic flexible integrated circuits. For example, traditional OLEDs only have the function of electroluminescence, but not the function of photoelectric conversion.

The invention provides an OLED device and a manufacturing method of the OLED device. The OLED device comprises a substrate, and a first electrode layer, an electron injection layer, an electron transport layer, an optically active layer, a hole transport layer and a second layer electrode layer which are arranged on the substrate in turn. The optically active layer includes an exciton control layer and an active material layer. The materials of the active material layer include a perovskite material and a small-molecule luminescent material, and the doping mole ratio of the small-molecule luminescent material is 0.1-15%. According to the OLED device and the manufacturing method of the OLED device of the invention, as the optically active layer composed of the exciton control layer and the active material layer is used in the OLED device and the materials of the active material layer include a perovskite material and a small-molecule luminescent material, the functions of electroluminescence and photoelectric conversion are achieved in the same device, the degree of function integration of the device is improved greatly, the process time is shortened, the manufacturing cost is reduced greatly, and the electroluminescent performance of the device is improved significantly.
Description
technical field [0001] The invention relates to the field of organic electroluminescence devices, in particular to an OLED device with dual functions of electroluminescence and photoelectric conversion and a manufacturing method of the OLED device. Background technique [0002] Organic optoelectronic devices have attracted more and more attention, especially organic electroluminescent devices (English full name is Organic Light-Emitting Diode, referred to as OLED), because of its solid-state light-emitting, wide viewing angle, wide color gamut, low power consumption, A series of excellent characteristics such as fast response speed, high and low temperature resistance, thinness and rollability, etc., are suitable for the requirements of low-carbon environmental protection and green life in today's world, and have been widely used in various fields of daily production and life such as flat panel display and solid-state lighting. [0003] In recent years, wearable electronic d...
