DuPont Microcircuit Materials (MCM) has introduced a new version of its front-side metallization pastes for crystalline silicon solar cells. Its Solamet PV18x series photovoltaic metallization pastes are expected to offer photovoltaic manufacturers improved productivity beyond that provided by Solamet PV17x series, according to MCM.
Solamet PV18A, the first product in the series, is tailored for optimal performance on mono-crystalline wafers with enhanced lightly doped emitters (LDEs). MCM adds that it is concurrently developing diffusion recipes in-house aimed at boosting solar cell efficiencies beyond the 19.3% level demonstrated with Solamet PV18A.
The company plans 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 multicrystalline cells with certain types of LDEs.
