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.

Cell manufacturers are constantly looking for low bowing aluminum pastes in order to save costs and move to thinner silicon wafers while maintaining low cell breakage rates,” said Patrick Boutard, PV Product Manager, Targray.

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. With the addition of this advanced family of Aluminum Paste, Targray has further enhanced its full-line of Photovoltaic materials and solutions currently used by leading solar cell and module manufacturers world-wide.

“Cell manufacturers are constantly looking for low bowing aluminum pastes in order to save costs and move to thinner silicon wafers while maintaining low cell breakage rates,” said Patrick Boutard, PV Product Manager, Targray. “They’re under constant pressure for efficiency gains to drive down the cost per watt. This new generation focuses specifically on this necessity, and our customers have reported a 0.05% to 0.1% increase in efficiency with this new line of 136 aluminum paste.“

Boutard adds: “PV cell manufacturers are currently exploring major technology improvements such as selective emitter, ion implantation, quasi-mono wafers, rear passivated cells and more to remain competitive. They often appreciate material changes that can quickly be qualified at no additional capital cost for modest electrical efficiency gains.”

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 3 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.

In addition to being a leading worldwide supplier of solar silicon and advanced materials to the Solar Industry, Targray is also a leading resource in helping Photovoltaic manufacturers to maximize cell and module quality and reliability, while lowering their cost per watt.
