On September 5, the first 5GW high-efficiency heterojunction battery and component project of State Power Investment Group New Energy Technology Co., Ltd. The maximum power is 700 W, and with continuous process commissioning, it is expected that the average power of mass production will exceed 720 W by the end of the year. On the same day, the company won an order for 140 MW photovoltaic cells. In January 2023, the first heterojunction high-efficiency component
of Longgang Base was formally established by Guodian Investment New Energy (Longgang) Co., Ltd., a wholly-owned subsidiary of Guodian Investment New Energy. It marks that the first 5G W high-efficiency copper grid line crystalline silicon heterojunction photovoltaic cell (C-HJT) and module production base of Guodian Investment New Energy has officially landed in Longgang City, Wenzhou, Zhejiang Province. The overall planning of the project covers an area of more than 400 mu, with a total investment of 6 billion yuan and an annual output value of 10 billion yuan. It will become the world's first large-scale production base of copper grid heterojunction batteries and components in the future.
In August, the company participated in the 2023 e-commerce centralized procurement project jointly organized by the Material and Equipment Branch of State Power Investment Group Co., Ltd. and Power Easy-to-buy (Beijing) Technology Co., Ltd., with a winning bid scale of 140MW, which fully demonstrates the good development prospects of Guodian Investment New Energy and the market's confidence in heterojunction batteries.
Guodian Investment New Energy 5GW High-efficiency Heterojunction Battery and Module Mass Production Equipment The biggest highlight of C-HJT battery technology independently developed
by Academia Sinica is the use of copper grid lines instead of precious metal silver grid lines , and the fine control of ultra-narrow copper grid lines improves the utilization rate of incident light on the front of the battery. The conversion efficiency of the battery is improved while the cost of the battery material is greatly reduced. Combined with the advantages of Tongshan wire heterojunction battery, such as simplified process flow, thin sheet, low temperature coefficient, high stability and high double-sided rate, its role in leading industry technology iteration and accelerating the development of photovoltaic industry will be further highlighted, and it will also be a strong support to achieve the goal of "3060" double carbon. The C-HJT
battery module was displayed
at the China International Trade in Services Conference in 2023.
