SILICON SOLAR CELL COATINGS

Ultrasonic spraying systems provide a low-cost solution for many solar cell applications. One of the typical applications is to spray anti-reflection and anti-reflection films on solar cell glass panels. Our ultrasonic nozzles can prepare uniform and dense nano-films such as TiO2 and SiO2 to improve the transmittance of glass. Another typical application is the preparation of hydrophilic and hydrophobic self-cleaning coatings on photovoltaic glass. Compared with traditional air spraying, ultrasonic spraying has significant advantages such as high-precision film thickness control, high uniformity, less splashing, and 4 times the raw material utilization rate. Compared with coating processes such as vacuum evaporation and CVD, ultrasonic spraying has a high cost performance, especially for large-area coatings, and the cost is greatly reduced, because ultrasonic spraying is regarded as a new large-scale glass coating Craft.

Another typical application of ultrasonic spray technology in solar panels is the coating of selective fluxes on panels. Ultrasonic spraying technology can achieve very precise loading and coating, and can minimize the waste of overspray, so as to prepare a dense, smooth and uniform cosolvent coating.
