Description

technical field [0001] Embodiments of the present invention relate to organic optoelectronic technology, and in particular to an organic optoelectronic device and a method for manufacturing the organic optoelectronic device. Background technique [0002] With the development of science and technology, organic optoelectronic devices have become an indispensable part of people's daily life. [0003] One of the most common problems in large-scale organic optoelectronic devices is that the optoelectronic properties of different optoelectronic units are different for the same driving signal. An important reason for this problem is that the resistance of the electrodes constituting the photoelectric unit is large, and the voltage drop of the electrical signal on it is large, resulting in different driving signals actually received by different photoelectric units. Therefore, the use of low-resistance transparent conductive films to make electrodes is an important part of realizin...
