Higher Cell and Module Efficiencies with Less Material Consumption Offer Near-Term Means for Solar Manufacturers to Improve Profitability
RESEARCH TRIANGLE PARK, N.C., Sept. 20, 2012 – DuPont Microcircuit Materials (MCM) has introduced its next-generation frontside metallization pastes for crystalline silicon solar cells. DuPont™ Solamet® PV18x series photovoltaic metallization pastes offer photovoltaic manufacturers improved productivity beyond that provided by Solamet® PV17x series, the current industry benchmark. Solamet® PV18A, the first product in the series, is tailored for optimal performance on mono-crystalline wafers with enhanced Lightly Doped Emitters (LDEs). PV18A is demonstrating efficiency gains despite significantly less material consumption when compared to Solamet® PV17F, further widening the gap in performance with other competitive products in the market. MCM is concurrently developing diffusion recipes in-house aimed at boosting solar cell efficiencies beyond the 19.3percent level already demonstrated with Solamet® PV18A.
“Solamet® PV17x series is the leading frontside photovoltaic metallization paste in the market today in large part because it was the first commercial paste that was able to unlock efficiency gains by being able to contact LDEs,” said Peter Brenner, global photovoltaic marketing manager, DuPont Microcircuit Materials. “Now Solamet® PV18x expands productivity by offering more with less - more efficiency from even better contact to LDEs together with less material required.”
Photovoltaic cell manufacturing is a challenging business where excess supply continually drives down cell and module pricing. Manufacturers are looking at ways to improve productivity by increasing cell and module efficiencies while keeping their costs in line with the rapidly reducing module average selling price.
Solamet® PV18x is the next-generation of the market-leading DuPont™ Solamet® range of frontside silver metallization pastes. PV18A is the first version of a new series, and plans are to continue to expand the series to address the specific needs of various market segments such as achieving even finer lines to support further reductions in the cost of ownership of multi-crystalline cells with high RSheet LDEs.
