DuPont(TM) Solamet® PV414 Photovoltaic Metallization Enables Thin Film Modules from Flexcell
Advanced Formulation Delivers Capability for High Speed Roll to Roll Processing of Flexible Solar Substrates
BRISTOL, U.K., - DuPont Microcircuit Materials (MCM) has introduced the low temperature processing DuPont(TM) 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.
"Roll to roll processing can offer huge productivity benefits to thin film photovoltaic module manufacturers like Flexcell, and we are very pleased that we were able to optimize the new Solamet® PV414 for their process," said Kerry Adams, business development manager - DuPont Microcircuit Materials. "Metallization pastes must be carefully adapted for rotary screen printing on thin film substrates to ensure material, and therefore cost, is not wasted and high efficiency is maintained. We will continue to expand Solamet® offerings for thin films as well as traditional crystalline silicon PV technologies to ensure high efficiency and lower overall system costs."
Standard metallization pastes do not typically perform well with rotary screen printing, so DuPont put its science to work to utilize the performance characteristics of the latest thin film metallization chemistry platform, Solamet® PV41x, and optimize it for this novel laydown technology. The extensive development work resulted in the formulation of Solamet® PV414 for rotary printing.
"Flexcell has become a best-in-class manufacturer of flexible thin film modules because of our unique manufacturing process and the commitment we have to using quality materials," said Diego Fischer, chief technology officer - Flexcell. "DuPont shares our commitment to quality materials and process optimization, and the collaboration on the project has been very successful."
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 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.
