Photovoltaic panel silver paste processing technology

As an important material in the production of silicon heterojunction solar cells, low-temperature curing silver paste is typically used for screen printing on both surfaces of solar cells and then forms silver grid electrodes through low-temperature metallization. . (MWT) cell designs. It is used as a via-fill and as a tab-bing Ag with a one s ep printing process. This paste may be cofired with standard DuPontTM Solamet® front side silver such as DuPontTM Solamet® PV16X or PV17X series, back side (p-type) Aluminum conductors such as DuPontTM So amet® PV3XX. . The metallization of heterojunction solar cells requires a further reduction of silver consumption to lower production costs and save resources.
