Focusing on CSPV! The Mingyang Voice at the Cutting-Edge of Heterojunction Technology

From November 2nd to 4th, the 19th China Solar Silicon and Photovoltaic Power Generation Conference (19th CSPV) was successfully held at the Xi'an International Conference Center. As an authoritative technical vane in the photovoltaic industry, this conference closely followed the cutting-edge technology and application of photovoltaics, attracting top experts in the industry, showcasing the latest research results and development trends at home and abroad, and creating a comprehensive and professional efficient communication platform.

On the afternoon of November 3rd, at the "Heterojunction Solar Cell Technology" sub-forum, Dr. Luo Qian, the dean of Mingyang PV Technology Research Institute, delivered a speech titled "New Metalization Route for Mingyang Heterojunction", focusing on the metalization technology route of heterojunction batteries, and shared the silver-grid metallization progress and copper-grid metallization scheme of Mingyang heterojunction batteries and their breakthrough points.

At the end of the speech, he envisioned that the low-silverization of heterojunctions is rapidly being realized through component technologies such as SMBB and 0BB, strongly supporting and expanding the current tens of GW capacity layout of the heterojunction industry.

Zeng Xinlin, Vice Director of Mingyang PV Product Management Center, delivered a speech titled "Manufacturing Progress of Mingyang Heterojunction Technology". Currently, the average efficiency of heterojunction solar cells produced by Mingyang Yancheng Heterojunction Battery Factory is stable at over 25.6%, and the mass production yield is stable at over 98%. The daily capacity of solar cells is more than 600,000 half cells. Through the breakthrough of key technologies, a series of achievements have been made in cost reduction and efficiency improvement.

He stated that compared to other cells, there is still a lot of room for improvement in the surface states of the silicon substrate of heterojunction cells. In the future research and development process, the combination of light conversion films and heterojunction can not only improve UV attenuation, but also increase module power.

In the future, Mingyang PV will continue to take technological innovation as the core, continuously optimize the technological level, effectively promote cost reduction, quality improvement, and efficiency enhancement, contribute Mingyang's strength to the development of the industry, fulfill the original intention and mission of "innovating clean energy for the benefit of human society", and use clean energy and low-carbon power to contribute to the earth we depend on for survival.
