A kind of transparent conductive film binary tree texturing equipment

Abstract

The invention discloses a binary tree texturing device of a transparent conductive film. The binary tree texturing device of the transparent conductive film comprises a frame, a spray texturing unit, a spray cleaning unit, a spray cleaning unit, a drying unit, a static elimination unit and a transmission unit. The invention solves the problem of rough spraying process in traditional texturing equipment and methods, uneven particle size of texturing liquid, and inhomogeneity of lateral texturing due to inconsistent flow of texturing liquid, which can improve production capacity and production The process is stable, the yield rate is high, and the performance parameters of transparent conductive film texturing are effectively improved, especially the transmittance, uniformity and haze, while reducing the use of texturing liquid and saving production costs.

Description

technical field [0001] The invention relates to the field of production and preparation of transparent conductive films, in particular to binary tree texturing equipment for transparent conductive films. Background technique [0002] Transparent conductive films have been widely used in solar cells, touch screen panels, displays and other industries, especially thin-film solar cells. Transparent conductive films are an important part of the structure of thin-film solar cells. As the front electrode of thin-film solar energy, the photovoltaic effect The generated charges are collected and guided to the storage battery or electrical appliances. Naturally, the transparent conductive film is required to have a sufficiently low sheet resistance, that is, a high conductivity; at the same time, because it is in the part of the thin film battery where the sunlight first passes through, the sunlight needs to pass through later. Only reaching the PIN junction or PN junction to realize...

AI Technical Summary

Problems solved by technology

Due to the larger particles of the texturing liquid produced by the spray head itself, it is easy to wash away the texturing surface under high pressure, so that the size of the surface etching pit is different, and it is difficult to control its geometric size; Upward, the spray texturing process is relatively rough, the particle size of the texturing liquid is uneven, and the flow rate of the texturing liquid is inconsistent, resulting in the unevenness of the lateral texturing, resulting in unevenness of light transmittance, sheet resistance, etc. along the side From the perspective of technology, industrial production requires stable product performance and uniform surface performance parameters, which is difficult to achieve on traditional spray equipment, and the controllability of the whole set of equipment is poor, which is not conducive to the improvement of process performance
