Metallisation paste producer Heraeus Photovoltaics has partnered with Taiwan-based solar cell producer Sunrise Global Solar Energy, a subsidiary of wafer producer Sino-American Silicon Products to maximise cell conversion efficiencies of its monocrystalline PERC cells beyond 21%. 

The companies are planning to optimise front side metallization paste formulations on Sunrise Global’s proprietary CELCO cells that are PERC (passivated emitter rear contact) based to push average cell efficiencies to 21.0%.

Heraeus Photovoltaics said it would work to customize their mainstream SOL9621 Series paste for Sunrise Global’s PERC cell design.

Dr. Weiming Zhang, Senior Vice President Research and Development, Heraeus Photovoltaics said, “Achieving maximum performance from cell designs cannot occur from innovation alone, which is why we relentlessly focus on a rapid R&D and commercialization strategy. We’re very excited to partner with Sunrise to jointly develop front-side metallization pastes and to advance future performance of their PERC product line because they share that same fast-track mindset.”

Sunrise Global was said to have already achieved peak cell efficiency of 21.5% in mass production of p-type monocrystalline cells.

The cell producer is also responsible for starting solar cell production (200MW) at SAS subsidiary in Germany, aleo solar. 

Heraeus Photovoltaics SOL9621 Series paste has claimed a world-record PERC efficiency of 21.7%.

Heraeus is also introducing new products such as the SOL9621P, which is a front-side paste designed specifically for PERC application.

Heraeus will also introduce its customised paste SOL9350C for p+ surface contact, which has demonstrated 0.1% higher cell efficiency and SOL9621L, which is specifically designed for n-type applications.
