DAS Solar and Hebei University Join Forces to Establish Photovoltaic Innovation Center

In a landmark collaboration, DAS Solar and Hebei University have signed a technology transfer agreement, marking the inauguration of the DAS Solar-Hebei University Photovoltaic Innovation Research Center. The signing ceremony, attended by Mr. Liu Yong, Chairman and President of DAS Solar, also involved discussions on collaborative research efforts.

As part of the agreement, Dr. Song Dengyuan, CTO of DAS Solar, and Professor Shan Yaojun, Vice President of Hebei University, inked a deal transferring technological achievements and patents related to Passivation Solution Efficiency Technology in Crystalline Silicon Cells. Dr. Song Dengyuan outlined the primary objectives of the newly established research center during the ceremony.

“Both parties would utilize the Photovoltaic Innovation Research Center to jointly address key core technologies and forefront common issues in the photovoltaic industry,” stated Mr. Liu Yong in his address. DAS Solar, known for its leadership in N-type technology, operates 10 photovoltaic manufacturing bases across various regions. The company boasts a CNAS lab and has achieved a production capacity of 30GW for high-efficiency cells and modules.

The collaboration signifies a long-term research partnership between DAS Solar and Hebei University, leveraging their respective strengths to explore innovative mechanisms for industry, academia, and research. DAS Solar has a strong commitment to intellectual property, with over 500 Chinese and international patents, and 256 granted patent applications as of the end of 2023.

The technology transfer agreement involves Hebei University transferring achievements and patents related to passivation solution efficiency technology in crystalline Silicon cells to DAS Solar. The research center aims to advance the application of this technology, facilitate large-scale production, and develop the next generation of passivation solutions to enhance efficiency.

The passivation solution efficiency technology developed by Hebei University is rooted in the electrochemical passivation principle, effectively addressing defects in efficient cell slices like TOPCon, ultimately enhancing module power. This cost-effective and easily industrializable technology, when combined with DAS Solar TOPCon 4.0 technology, promises significant efficiency improvements for high-efficiency modules.

DAS Solar’s previous collaboration with the University of New South Wales in Australia focused on researching 40% efficient SFOS cells. Through the partnership with Hebei University, DAS Solar aims to accelerate its innovative advancements in N-type technology, contributing to the sustainable development of international photovoltaic technology.
