Heraeus signs silver paste development partnership with China’s Solar Space


Heraeus, the German-headquartered developer of silver pastes for the solar industry, has announced this week it has signed a cooperation agreement with Solar Space (Zhonghui Photovoltaics) to develop high-performance silver paste solutions.

The collaboration will see both firms work on regular processes, dual printing and other new technologies and techniques designed to deliver optimized metallization paste performance and application for the solar sector.

Hereaus will also work closely with Solar Space to identify solar cell production improvements at its Jiangsu facility. Solar Space aims to increase its cell capacity to 10 GW by 2020, with the goal of adding at least 3 GW of extra capacity in 2017 alone.

The two firms have long cooperated, with Solar Space first adopting Heraeus’ 9411 silver paste for its cells, through to the most recent iteration, the SOL9641BX paste.

It is through using Heraeus’ current paste that Solar Space says it will be able to “improve its competitiveness” in the solar industry. “Together with Heraeus expertise, we expect further breakthroughs in performance through optimization of the SOL9642BX product and production process,” said Solar Space general manager Liu Guyan.
