Jolywood and Heraeus Photovoltaics Form New R&D Cooperation on Future High Efficiency N-Type Metallization Solutions

The innovative n-type paste solution for frontside and backside metallization provided by Heraeus enables 21% frontside and 19% backside cell efficiencies in mass production.

Heraeus Photovoltaics, a leading provider of technology and service solutions for the renewable energy industry, and Jolywood, a leading manufacturer of advanced solar cell technologies, signed a strategic R&D cooperation agreement to develop next generation metallization solutions for n-type mono bifacial solar cells to significantly improve performance and costs efficiencies.

Jolywood pioneers the PV-industry in high efficient n-type mono solar cells for bifacial glass/glass-module applications. It awarded Heraeus Photovoltaics last year as its preferred paste supplier as the company focuses on high efficiency mono solar cell architectures. The innovative n-type paste solution for frontside and backside metallization provided by Heraeus enables 21% frontside and 19% backside cell efficiencies in mass production. Under the agreement, both companies share a close cooperation regarding the development of silver pastes and a strong supply relationship to further enhance the efficiencies of bifacial n-type mono cells, which have started becoming an industry trend.

Mr. Lin Jianwei, Chairman of Jolywood, highlighted, “Jolywood is a pioneer in the photovoltaic industry and engaged in such fields as backboards, cells, and power plant investment. Especially in Type-N high-performance mono double-sided cells, we offer huge advantages. To further develop our leading technologies, we are developing strong cooperation with high-quality partners like Heraeus Photovoltaics.”

General Manager Liu Yong of Jolywood said, “Since the establishment of Jolywood, we have been dedicated to exploring the cutting-edge technologies of the industry. The silver paste for the front and back side provided by Heraeus Photovoltaic supported the mass production of Jolywood Type N double-sided cells last year. By our development cooperation we hope to continuously increase the conversion efficiency of bifacial cells.”

Andreas Liebheit, President Heraeus Photovoltaics, comments, “We are very happy to see Heraeus Photovoltaics and Jolywood jointly driving innovations in the PV industry. Our cooperation is another good example how our technology leadership helps our customers to overcome the performance and cost challenges of cutting-edge solar cell technologies.’’

Weiming Zhang, Chief Technology Officer, Heraeus Photovoltaics Global Business Units, adds, “The n-type mono double-sided cell currently produced by Jolywood adopts the whole set of our SOL9360A new generation n-type metalizing platform. Our cooperation marks a solid foundation to further drive joint innovation of next generation metallization solutions for high-efficiency solar cell technologies.”
