Preparation of TCO Coating by Spraying PET Film

Ultrasonic thin film spraying equipment: a revolutionary force in the preparation of TCO coatings from PET films.

In the rapid development of the new energy and optoelectronic industries, transparent conductive oxide (TCO) coatings have become key materials in fields such as photovoltaic modules and display screens due to their high transmittance and excellent conductivity. TCO coating is usually composed of materials such as indium tin oxide (ITO), zinc oxide (ZnO), etc. It acts as an “energy bridge” for optoelectronic devices, ensuring efficient light penetration and rapid current conduction. Its performance directly affects the photoelectric conversion efficiency and service life of the product.

The traditional TCO coating preparation method has problems such as poor coating uniformity, high cost, and complex process. The use of ultrasonic thin film spraying equipment to prepare TCO coatings on PET films brings a new solution to the industry. PET film is lightweight and flexible, making it an ideal substrate for preparing flexible TCO coatings. Combined with ultrasonic spraying technology, it can break through the limitations of traditional rigid substrates and meet the development needs of flexible electronic devices.

Ultrasonic thin film spraying equipment utilizes high-frequency ultrasonic vibration to atomize TCO coating solution into micrometer or even nanometer sized droplets. These small and uniform droplets can be accurately and uniformly deposited on the surface of PET film, forming a dense and thickness controllable TCO coating. Compared to traditional methods, the TCO coating prepared by this device not only exhibits excellent transparency and conductivity, but also effectively reduces material waste and lowers production costs.

At the same time, the equipment is easy and convenient to operate, and the spraying parameters such as atomization frequency, spraying time, solution concentration, etc. can be flexibly adjusted. TCO coatings that meet specific needs can be customized according to different application scenarios. Whether it is scientific research institutions exploring new TCO materials or enterprises producing flexible photovoltaic modules and intelligent displays on a large scale, ultrasonic film spraying equipment provides reliable guarantees for the preparation of TCO coatings on PET films with high efficiency and stable performance, helping the optoelectronic industry reach new heights.
