introduce:
Ultrasonic spraying techniques can successfully deposit TCO coatings, buffer layer coatings, PEDOT, and active layers in perovskite solar cell fabrication. OPV, CIG, CdTE, CzT, perovskite and DSC are some solutions or suspensions that can be deposited using ultrasonic spray technology in the fabrication of thin film solar cells. Ultrasonic atomizing nozzle systems cost a fraction of the cost of CVD (chemical vapor deposition) and sputtering equipment, reducing the cost per watt of manufacturing thin-film solar cells while still delivering high cell efficiency.
principle:
Ultrasonic nozzles use piezoelectric transducers to convert high-frequency sound waves into mechanical energy for longitudinal high-frequency vibration. This longitudinal upward and downward movement generates standing waves in the applied liquid film at the hard end of the ultrasonic nozzle, and the amplitude of these waves can be Controlled by an ultrasonic generator. The liquid waves extend upward from the tip of the ultrasonic nozzle until they are separated into uniformly sized droplets with little kinetic energy. Overmolding gas or ambient air can easily wrap droplets into the desired shape and velocity for a variety of spray applications.
Forming system:
The soft, low-velocity spray produced by ultrasonic nozzle spray forming systems often requires air forming to meet the needs of the application, especially where high precision or uniform deposition is required. Shape the atomized spray into specific patterns that allow precise control of the atomized spray using low pressure air. The spray pattern can also be integrated into a complete coating system using multiple nozzles mounted in series.
nozzle:
The use of titanium alloy ultrasonic nozzles overcomes the technical difficulties of spraying highly corrosive acids. The nozzles are made of corrosion-resistant titanium alloy materials. Even when spraying highly corrosive hydrochloric acid or hydrofluoric acid solutions, they will not be blocked and can be reused and used repeatedly. Long life and provide superior acoustic performance. We provide six types of ultrasonic atomizing nozzles: long mouth type - wide spray type - probing type - scattering type - gathering type - line spray type to deal with different applications.
Advantage:
1. The spray pattern is easy to form, suitable for precise coating application.
2. Any shape object can be sprayed to form a uniform micron-level coating.
3. Self-cleaning, non-clogging ultrasonic nozzles that reduce downtime in critical manufacturing.
4. Highly controllable spray volume, more reliable spray quality.
5. Low energy consumption, high atomization efficiency, and less restriction on atomized liquid.
6. High transmission efficiency, which can reduce waste and air pollution caused by back spraying, and save a lot of cost.
7. The nozzle is made of titanium alloy material, which has the characteristics of high strength and corrosion resistance.
8. Low maintenance time, further increase productivity.
9. High-precision pressure reducing valve and liquid control valve to achieve gas-liquid coordination at various speeds.
