Abstract

The invention discloses a transparent conductive film, a preparation method thereof, application, and a photoelectric device containing the transparent conductive film. The transparent conductive filmsequentially comprises a first conductive film layer, a transparent substrate layer and a second conductive film layer which are overlapped with one another; a plurality of through holes are formed in the transparent substrate; the hole diameters of the through holes are 0.5-100 microns; when two or more through holes are formed in the transparent substrate, the distance between the center pointsof any two adjacent through holes ranges from 0.1 mm to 100 mm; the volume ratio of the through holes to the transparent substrate ranges from 0.0001% o to 2.5%; the through holes are filled with conducting media. According to the transparent conductive film, bulk phase conduction can be realized on the basis of not influencing the light transmittance of the material, the conductive performance is uniform, more signals can be generated, diversification of photoelectric products is realized, the erasable range of a conductive liquid crystal board can be controlled, the preparation process is simple, and industrial large-scale production is facilitated.

Description

technical field [0001] The invention relates to the field of optoelectronic products, in particular to a transparent conductive film, its preparation method, application, and an optoelectronic device containing the same. Background technique [0002] Optoelectronic products require the penetration of light and the conduction of electricity. Therefore, transparent conductive films are the basis of optoelectronic products. Optoelectronic products such as conductive liquid crystal panels, flat panel displays, touch panels, solar cells, electronic paper, and OLED lighting need to use transparent conductive film. [0003] The existing transparent conductive film is generally by magnetron sputtering ITO (indium tin oxide) layer on the surface of transparent film materials such as PET (polyethylene terephthalic acid), PC (polycarbonate) and PI (polyimide), In order to achieve the effect of surface conductivity. However, this kind of transparent conductive film can only achieve on...
