Ferro Electronic Materials has launched two new print-on-print metallization pastes: NS 33-514 and NS 33-515. According to the company, these pastes have optimized inorganic and organic properties that make them compatible with the double-printing (print-on-print) process.
Double-printing of metal grid lines permits solar cell manufacturers to print taller, narrower lines, reducing the shadowing effect caused by wide grid lines, while enhancing electrical conductivity, the company says. Double-printing is experiencing strong growth due to the potential for better print resolution and subsequent increases in efficiency.
Ferro's NS 33-514 and NS 33-515 are capable of printing grid lines that are 70 microns wide, with a greater than 0.3 aspect ratio.
