DuPont PV metallization paste formulated for R2R thin-film PV fab

DuPont Microcircuit Materials (MCM) introduced the low-temperature processing DuPont Solamet PV414 photovoltaic (PV) metallization paste for application via rotary screen printing.

September 2, 2011 — DuPont Microcircuit Materials (MCM) introduced the low-temperature processing DuPont Solamet PV414 photovoltaic (PV) metallization paste for application via rotary screen printing. The paste can be integrated into roll-to-roll (R2R) processing systems to fab thin and flexible solar cells and modules.

Swiss amorphous silicon (a-Si) thin film PV maker Flexcell qualified the DuPont Solamet photovoltaic metallization paste in its thin film R2R process. The solar cells are used in building integrated PV (BIPV) and mobile solar applications.

The metallization paste is formulated to avoid waste during high-speed rotary screen printing. This is DuPont’s first Solamet paste designed for use in R2R processing. Printability and line resolution are maintained in the processsing, and the formula adheres to transparent conductive oxide (TCO) on the substrate. It touts low contact resistance and outstanding conductivity.  

Additional products in the Solamet PV41x low temperature 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.

DuPont Microcircuit Materials makes specialized thick film compositions for the photovoltaic, display, automotive, biomedical, industrial, military, and telecommunications markets.
