FUJIFILM Dimatix Materials Printer DMP-2850
The operational procedure of an inkjet printer mainly involves the expulsion of a fixed volume of ink in a chamber through a sudden, quasi-adiabatic reduction of the camber volume via piezoelectric action. By adjusting the printing parameters, well-defined patterns can be printed on the substrate. In recent years, significant advancements have been made in the development of printers and printheads for functional printing purposes. Inkjet printers have gained prominence in the fabrication of solar cells due to their inherent advantages of rapid, precise, and maskless patterning. Inkjet printing technology has been utilized for texturization, doping, masking, and metallization for solar cells, employing different types of inks.
