For solar cell metallization applications, thick film paste is a suspension of a functional (conductive) phase, binder, vehicle and additives. Silver is the most common conductive filler used for front contact paste. The binder is composed of a glass frit that is used to bind the functional phase to the silicon wafer.
Screen printing is the most cost efective method for producing c-Si (crystalline silicon) solar cells. Thick film and screen-printing technology are well established and require relatively low capital investment. Solar cells manufactured using this metallization technique are easy to mass produce and are highly reliable with low waste.
Product DescriptionDuPontTM Solamet® PV701 photovoltaic metallization paste is a highly conductive silver composition, developed for via filling in silicon wafers to interconnect the front side grid with the back side using the Metal Wrap Throug (MWT) cell designs. It is used as a via-fill and as a tab-bing Ag with a one s
The paste viscosity will decrease as it passes through the screen. As the screen is peeled away from the substrate, the paste will flow together around the mesh while recovering to near resting viscosity.
