Heraeus Photovoltaics releases new generations of high-efficientmetallization pastes at SNEC 2017 in Shanghai

Five new silver pastes guarantee substantial efficiency boosts for established andemerging solar cell technologies

SHANGHAI, CHINA – April 19, 2017 – Heraeus Photovoltaics, the worldwide leading supplier ofmetallization solutions to the PV industry releases five new metallization pastes at the 11th SNECInternational Photovoltaic Power Generation Conference & Exhibition 2017 in Shanghai andcontinues to provide solar cell manufacturers with high-efficient solutions for different solar celltechnologies.

Unrivalled efficiency boost for PERC cells with SOL9641B

On mono- and multi-crystalline ULDE and PERC cells Heraeus’ brand new SOL9641B series withimproved finger geometry helps boosting efficiencies significantly by up to 0.2%. Better metallizationcontact and less shading enable this efficiency boost. The metallization paste demonstrates superiorcontact behavior on demanding emitters such as ultra-lightly doped emitters (ULDE). In addition, theorganic vehicle system for ultra-fine line printing has been improved.

A unique glass frit developed and produced by exclusively Heraeus Photovoltaics enables a widerfiring window toward lower temperature side. It is tailored to the low temperature processing needs ofPERC solar cells and can be paired with the award winning SOL326 PERC backside paste to realizehigher efficiencies and mass production yield.

All the advantages with the double-print packages 9642A and 9642B

Evolutionally upgraded double print packages 9642A and 9642B carry all the advantages of theSOL9641A and 9641B platforms. Outstanding efficiency gain of up to 0.1% enabled through improveddouble-print Ultra-fine-line (UFL) printability with higher aspect ratio. The double-print package alsoboasts a “zero” EL defect in mass production and is also an A+A' and A+B solution for higher FillFactorand Voc. The SOL9642A package with excellent adhesion is tailored for mono and multi blacksilicon wafers as well as PERC.The 9642B package features a perfectly balanced metallizationcontact and passivation damage as well as low firing temperatures, making it compatible with monoPERC.

9641A for challenging black silicon solar cells

The nano-structured black-silicon texturing surface is challenging for metallization pastes. HeraeusPhotovoltaics offers with 9641A for black silicon a specially re-designed formula, which features aunique glass chemistry and fine-tuned organic media matching to fit to the particular surfacemorphology of black silicon. It provides an optimal amount of silver crystallites on the silicon surfacesfor a well-balanced metallization contact and Voc. Furthermore it features superior adhesion andreliability and a wide firing window, which makes 9641A black silicon specifically suitable for PERCcolar cells.

N-type 9360A – higher efficiency, less paste usage

The SOLA9360A breakthrough p+ emitter metallization paste for n-type cells offers excellent contactformation as well as improved fine line screen printing capabilities, especially on high mesh, thinnerwire screens and 28 ?m screen openings. Due to reduced finger width, an efficiency gain of 0.1% canbe achieved. Customers have also confirmed higher efficiencies with significantly less past usage,which translates into a significant reduction in a cell’s cost per watt. In addition, the n-type SOL9360Aprovides reduced contact and line resistivity as well as minimized metallization damage and a higher fill factor (0.42) due to high aspect ratio. The metallization paste is available as double print packagein combination with 9622B.

SOL9641AX/BX – made for knotless screen printing technologies

The new SOL9641AX/BX series is designed to realize the full advantages of knotless printingscreens, also known as zero degree mesh screens. Different from the conventional wire mesh thisemerging technology gives the paste more room to pass through. The printability of SOL9641AX/BXhas been perfectly tailored to this specific requirements of knotless screens. It features a unique pasterheology, enabling a significant higher aspect ratio on ultra-fine-line fingers compared to conventionalpaste used for knotless screens. An outstanding 0.1% efficiency gain can be achieved and the pastesare perfectly suited also for black silicon texturing.

“Metallization pastes are the core competency at Heraeus Photovoltaics. Since years we partner withour customer to achieve significant leaps in efficiency and we continue to do so with a new generationof metallization pastes for different solar cell technologies. With our high-efficient solutions andservices, we play an important role in making renewable energies the cheapest energy source in thenear future,” says Andreas Liebheit, President of Heraeus Photovoltaics.
