Photovoltaic Coating System
HAVERHILL, Mass., July 21, 2008 – Ultrasonic Systems has introduced the PV360 high volume production coating system for coating solutions to photovoltaic wafers.
Using the company’s nozzleless spray technology, the system applies a thin, uniform layer of phosphoric acid, phosphoric oxide and other proprietary coatings for the production of solar cells. The self-cleaning system has a material transfer efficiency of up to 99 percent and a film thickness down to sub micron. 
The PV360 also consists of a nonmetal conveyor, either mesh belt or plastic roller, to transport the wafers. To ensure that coating is not transferred to the bottom side of the wafers, the conveyor uses a water-based cleaning system and an IR drying system. The conveyor is 914 mm wide and can accommodate up to six rows of 125 mm wafers. It can also transport wafers at a constant speed of up to 890 mm/minute.
The spray head has a rectangular, lineal spray pattern at a width up to 152 mm. To provide desired coating deposition, the liquid flow rate and traversing speed are independently adjustable. The motion of the spray head is synchronized to the conveyor speed and the width of the spray pattern.
