DuPont Debuts Low-Temperature Metallization Paste


DuPont Microcircuit Materials has introduced a low-temperature processing paste. DuPont Solamet PV414 photovoltaic paste is designed for rotary screen printing to enable high-speed roll-to-roll processing of thin-film and flexible solar cells and modules, the company says.

The new offering was recently qualified at Flexcell, a Switzerland-based producer of flexible amorphous silicon thin-film modules for building-integrated photovoltaics and mobile solar chargers.

According to DuPont, Solamet PV414 is engineered to ensure superior printability and line resolution while maintaining adhesion to the transparent conductive oxide layer, low contact resistance and strong conductivity.
