Aluminum paste for solar cells

Targray Technology International announces the availability of Giga Solar Materials Corporation’s next generation of aluminum paste for mono- and multi-crystalline silicon solar cells. The new line of AI Paste has been optimized for a variety of requirements, including higher efficiency, higher peak firing temperatures, hot water test, and superior adhesion. Rear aluminum paste must provide an excellent back surface field to enable high cell efficiency. It must also be highly compatible with a variety on silicon wafers, and have excellent adhesion qualities to overcome environmental stress testing at the module level. Printability is another important property in that a paste must transfer in a reliable and consistent manner for tight manufacturing controls and performance. Finally, it must be compatible with a variety of front and back silver paste by performing well under a wide process window for co-firing of all three pastes. Targray’s new generation of paste satisfies all of these criteria with excellent efficiency, high material compatibility, adhesion strength, and a wide process window.
