DuPont Microcircuit Materials (DuPont) has added two new products to its lineup of frontside silver metallization pastes for crystalline silicon solar cells. DuPont Solamet PV18H and PV18J PV metallization pastes offer solar cell manufacturers improved efficiency and profitability.
“The DuPont Solamet PV18x series offers more efficiency with less material required, and we continue to innovate and build on the series,” says Peter Brenner, global photovoltaic marketing manager for DuPont. “These two newest offerings demonstrate a range of technical properties to meet different customers’ manufacturing process requirements.”
DuPont has added two new products, Solamet PV18H and PV18J, to its leading lineup of frontside silver metallization pastes, offering improved efficiency and profitability for crystalline silicon solar cell manufacturers.
The Solamet PV18x series products deliver a step change in the power output of solar panels by improving the conversion efficiency of solar cells. This is due to proprietary Tellurium technology, which is only licensed and available from DuPont, and has been instrumental in unlocking efficiency gains by more than 0.5% by allowing contact to enhanced lightly doped emitters.
Compared to industry standard pastes on multi-crystalline solar cells, Solamet PV18H and PV18J can boost conversion efficiency by an additional 0.15%, as well as enabling extremely fine line printability down to 35 microns. In addition, up to 30% less material usage is required with these new materials, resulting in significant savings for manufacturers.
Solamet PV18H further enables excellent contact resistance to enhanced lightly doped emitters on mono-crystalline solar cells to maximize power output, says DuPont. The company also says that Solamet PV18J demonstrates superior adhesion performance even with thinner busbars, and improves processing with excellent solderability and a wide solder temperature window.
