Purchased from Q-Cells.
Fully Automated Line Polycrystalline Solar Cells
16% plus efficiency cells

This system is used for the production of solar cells by the silk-screen printing process.
This process allows the production of:
-Conductors
-Resistors
-Dieelectrics
-Glass protections
-Cross-overs
The loading of the system is carried out by a conveyer with vision system. Wafer cells arrive from a conveyer to a Baccini
conveyer and here, by a vision system the cells are aligned and put on a walking beam, by adjusting the speed of the first
conveyer you can obtain loading heaps of 4 or 6 cells.
Printing head resolution is approx 0.5nm
