The Low Temperature Processing DuPont™ Solamet® PV414 Photovoltaic.
DuPont Microcircuit Materials (MCM) (Bristol, UK) has introduced the low temperature processing DuPont™ Solamet® PV414 photovoltaic (PV) metallization paste designed for rotary screen printing to enable high-speed, roll-to-roll processing of thin and flexible solar cells and modules. The new offering was recently qualified at Flexcell, a leading Swiss producer of flexible amorphous silicon thin film modules, for building integrated photovoltaics (BIPV) and mobile solar chargers. Solamet® photovoltaic metallization pastes are key to higher efficiency and lower system costs for both crystalline silicon (c-Si) and thin film PV.

Solamet® PV414 is engineered to ensure superior printability and line resolution while maintaining excellent adhesion to the Transparent Conductive Oxide (TCO) layer, very low contact resistance, and outstanding conductivity. Additional products in the Solamet® PV41x lowtemperature metallization family are adaptable to Copper Indium Gallium Selenide (CIGS), Cadmium Telluride (CdTe), Silicon Heterojunction (SHJ), Dye Sensitized Cells (DSC), and Organic Photovoltaic (OPV) technologies.
