Ultrasonic Systems launches spray system for CdTe PV module making

Ultrasonic spray coating equipment maker Ultrasonic Systems Inc (USI) of Haverhill, MA, USA has launched the PV-480 system for high-volume, precision coating of glass plates in cadmium telluride (CdTe) photovoltaic module manufacturing.

The PV-480 leverages USI’s proprietary, nozzle-less ultrasonic spray head technology for what is claimed to be thinner, more uniform coating deposition versus conventional spray technologies. Optimized for high-volume in-line manufacturing, the system can process glass plates up to 48 inches wide at speeds of up to six feet per minute.

The PV-480 delivers liquid coating with transfer efficiencies in excess of 90%, using a traversing Ultra-Spray blade head. The versatile system suits the application of cadmium chloride solution and anti-reflective coatings, as well as other low-viscosity liquids. It can be operated in-line or stand-alone, and is easy to control via a touch-screen user interface. USI says that its coating systems are industry proven, with more than 2500 installed worldwide in multiple markets.

“The PV-480 extends our unique nozzle-less spray head technology to glass plate applications critical to CdTe thin-film solar production,” comments says president Stuart Erickson.
