Ultrasonic Spray System for Solar Applications

Ultrasonic Systems Launches New High-Efficiency Spray System for Solar Applications
The UAM6000 delivers high volume, precision coating for PV cell manufacturing requirements

CHEERSONIC, a leading manufacturer of high-performance ultrasonic spray coating equipment, announces the release of the UAM6000 for PV wafer coating applications. The UAM6000 leverages nozzle-less ultrasonic technology for highly uniform, thinner coating deposition when compared to conventional spray technologies. Optimized for high-volume, in-line manufacturing, the UAM6000 can process up to 4,300 wafers (125mm) per hour. The UAM6000 features a wafer dryer system, dual metering pump liquid delivery system, and state-of-the-art control system with touch-panel interface. The UAM6000 increases manufacturing quality, efficiency, throughput, and reliability for the in-line thermal diffusion and laser doped selective emitter (LDSE) processes.

The UAM6000 delivers liquid coating with transfer efficiency of 95-99%, utilizing a traversing ultrasonic nozzle for greater control of film thickness, down to the sub-micron level. Plus, it offers the versatility to handle the transfer of phosphoric/boric acid and phosphoric oxide dopants, as well as other proprietary coatings.
