Ferro Electronic Materials offers two new print-on-print metallization pastes. NS 33-514 and NS 33-515 pastes have optimized inorganic and organic properties that make them compatible with the double-printing (also known as print-on-print) process. The 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 new pastes are capable of printing grid lines that are 70 microns wide with a greater than 0.3 aspect ratio.

"Ferro has been engaged with double-printing applications for more than five years," said Todd Williams, business manager. "This technology is experiencing strong pull due to the improvements in electrical efficiency possible from the higher aspect ratios that can be produced."
