Spraying Photovoltaic Cells
Spraying Photovoltaic Cells – Ultrasonic Spray Coated Layers – Cheersonic
With the rapid development of the photovoltaic industry today, the precision of the cell manufacturing process directly affects the photoelectric conversion efficiency and product yield. The ultrasonic spraying system launched by Cheersonic Intelligent Equipment has brought a revolutionary coating solution to the photovoltaic cell production line, perfectly solving the pain points of traditional spraying methods in terms of uniformity and material utilization.
Principles and core advantages of ultrasonic spraying technology
Ultrasonic spraying technology uses high-frequency vibration (40-120kHz) to break the slurry into micron-sized droplets, and achieves uniform deposition through precise control. Compared with traditional air pressure spraying, it has the following outstanding advantages:
- Ultra-uniform coating: It can prepare uniform thin films of 5-50μm to ensure the consistency of the thickness of the conductive layer on the surface of the battery
- Ultra-high material utilization rate: The spraying efficiency is more than 90%, which greatly reduces the consumption of expensive materials such as silver paste
- Non-clogging design: Especially suitable for high-solid content slurries containing nanoparticles
- Intelligent control: It can be integrated into the automated production line to achieve precise online spraying
Key application scenarios of photovoltaic cell production lines
- Precision coating of conductive silver paste
In the production of high-efficiency batteries such as PERC and TOPCon, ultrasonic spraying can achieve ultra-fine printing with a grid line width of <30μm, increase the light receiving area, and ensure conductive performance. - Preparation of anti-reflective coating
It is used to deposit anti-reflective films such as SiNx, with a film thickness uniformity of up to ±3nm, which significantly improves the light absorption efficiency. - Manufacturing of new perovskite cells
It is particularly suitable for the gentle deposition of sensitive functional layers such as perovskite layers and hole transport layers to avoid damage to fragile substrates by solution spraying.
