Problems solved by technology

Moreover, the film made by the high internal pressure of the nozzle can ensure uniformity, otherwise it is easy to form zebra stripes and the uniformity is not good
At the same time, at high temperature, the multi-slit nozzle is easy to destroy the uniformity of the gas injection, so that the thickness and performance of the formed film are not uniform.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing:

[0017] The special nozzle for preparing transparent conductive film by ultrasonic rapid deposition method, which includes air inlet, air inlet pipe, nozzle, and nozzle; out;

[0018] Its characteristic is: the chemical solution is atomized by the ultrasonic spraying method, and after entering the nozzle 3 evenly through the air inlet 1 and the air inlet pipe 2, it is finally sprayed evenly on a surface of 20×20cm through the nozzle. 2 on a large area glass substrate.

[0019] The nozzle height is 150mm, the width is 200mm, the thickness is 5mm, the nozzle is a slit orifice, and the area of ​​the nozzle slit is 20×1.5mm 2 .

[0020] The upper part of the nozzle is designed with a slope. The ratio of the volume of the nozzle 3 to the area of ​​the nozzle 4 determines the pressure of the nozzle 4. The atomized gas can be sprayed on a uniformly moving and heated glass substr...

Abstract

A special spray head for preparing large-area transparent electrically conductive film by high-speed ultrasonic deposition method features that the atomized raw material comes in its air inlet tube, is divided into three channes, and finally sprayed onto a large-area (20X20 sq.cm) glass substrate via the slits.

Description

technical field [0001] The invention relates to a special nozzle for preparing a large-area nanometer transparent conductive film, which is used in the coating field of optoelectronic thin film materials. Background technique [0002] As a new type of green energy, solar energy has the characteristics of infinity, matching with conventional power grids, and no geographical application restrictions. It has become the first choice for governments to develop new energy sources. Solar cells can directly convert solar energy into electrical energy without any pollution to the environment. Amorphous silicon thin film solar cells have good semiconductor optoelectronic properties, low cost, and large-scale production, which make them have outstanding advantages in the competition with other semiconductor devices. The thin-film battery manufacturing process is formed by sequentially depositing thin-film photovoltaic materials on cheap substrates such as glass and plastic using low-t...
