Can Ultrasonioc Nozzle Be Used for Solar Cell Spraying？

Solar cells are devices that use semiconductor materials to convert photon energy into electrical energy, and ultrasonic spraying technology can be used to prepare solar cells. The photoelectric conversion efficiency and life of solar cells are directly related to the quality of their surface coating. Ultrasonic spraying technology can evenly coat a layer of transparent conductive oxide coating on the surface of the electrode to improve the conversion efficiency of the cell, and can more accurately control the coating thickness, thereby reducing the coating cost.

Ultrasonic spraying is very suitable for depositing solar cells, fuel cells, silicon cell coatings, and is increasingly used in research and production spraying processes. Ultrasonic spraying technology can be used to deposit uniform and extremely thin coatings on substrates of any width. Ultrasonic spraying technology can produce very thin coatings with extremely high uniformity, which improves both electron conversion and transport.

How ultrasonic spray nozzle working?

Ultrasonic nozzles operate by converting high frequency sound waves into mechanical energy that is

transferred into a liquid, creating standing waves. As the liquid exits the atomizing surface of the nozzle, it is broken into a fine mist of uniform micron sized

droplets.

Every ultrasonic nozzle operates at a specific resonant frequency, which dictates the median droplet size. Droplet sizes have little variance, and can be mathematically calculated to fall within a tight predicted drop distribution. For example, a 120 kHz nozzle produces a median drop size of 18 microns (when spraying water). The higher the frequency, the smaller the median drop size.

How to select the spray nozzles?

1. The viscosity of the material  

2. The request particle size

3. Temperature of coating request

4. Width of coating

5. Height of coating

6.  Capacity of coating

7. Any solid phase

8. Whether the material is corrosive or not

Industrial syringe pumps are a specialized type of syringe pump designed for use in industrial and manufacturing settings, rather than just in medical or research applications.

The application of ultrasonic spraying technology in the medical industry not only improves the manufacturing level of medical devices, but also brings safer and more effective medical solutions to patients. Medical manufacturing enterprises need to actively embrace technological innovation, strengthen technology research and development and personnel training, take ultrasonic spraying technology as a breakthrough, promote the development of medical manufacturing to the direction of precision and intelligence, and make greater contributions to the cause of human health. With the continuous progress of technology, ultrasonic spraying technology will play a more important role in the field of medical manufacturing, and promote the medical industry to a higher level.
