High Volume Production
Inkjet Printer
System Description
The IP3000 Industrial Inkjet Printer is designed to run high volume mass production for various applications within the solar industry.
The advantages of ink-jet printing with small feature sizes, exact positioning and contactless deposition are important for high efficiency
solar cells. (e.g. thin contact lines, local etching and low breakage rates).
Combined with OTB Solar - Roth & Rau’s unique Single Step Selective Emitter Process which is based on direct printing of dopant
material, the IP3000 production system delivers lowest cost of ownership. The doping level is determined by selecting the related ink
composition. The IP3000 inkjet printer is fully compatible with Roth & Rau automation solutions.
Solar Applications
Single Step Selective Emitter by direct dopant ink
Mask printing with hot-melt or UV curable inks
Contact patterns and dopants with nano particle inks
