“…For example, by reducing the amount of Ag paste for metallization will reduce the $=watt cost of solar electricity. [18][19][20][21] The focus of this paper is therefore, to reduce the amount of silver from 100-130 mg with screen-printed technology to <80 mg using an alternative metallization dispensing, such as the inkjet printed technology.…”

Multicrystalline silicon solar cells with average efficiency of 17.4%, using only 74 mg of silver, are reported in this paper. The uniqueness of the digital inkjet metallization include: creation of precise gridlines (width of 47 µm and height of 45 µm) and ability to control the amount of Ag paste dispense per wafer. Because of the precision of each gridline width and height, the front gridline shading was lower than the screen-printed counterpart, which also used >120 mg of Ag. A combination of multicrystalline substrate and less amount of silver used in conjunction with >19% can lead to a lower $/W solar cell.
