Yesterday, a stone in Longji stirred up a thousand waves. What is different
from the previous TOPCon and heterojunction disputes is that this is not the third generation " singing about TOPCon and betting on BC, and Longji decided to focus on HPBC. At the same time, TBC based on TOPCon and HBC based on heterojunction are reserved for development.
On the same day, Jingke showed different opinions, saying that it was firmly optimistic about the prospects of TOPCon in the next 3-5 years, and broke back a game for TOPCon. Who Is the Future of Photovoltaic Cells in the Renewed
Technological Debate? Longji, Jingke outside Tongwei, Jingao, Tianhe, Atlas and other photovoltaic leaders how to look at? Ccement. Com/richtext/IMG/ha2d384vmg51694049138595.
At the same time, Tongwei Company actively carries out the pilot test and transformation of the mainstream technology route of the next generation of mass production, based on the cost-effective advantages of TOPCon battery technology. The company has 25 GW TNC battery (TOPCon) production capacity, and the conversion efficiency and yield of mass production are in the leading level in the industry.
At the same time, the company's HJT battery technology has also made many key progress in reducing costs and increasing efficiency, and synchronously maintained the research and development of full-back contact and perovskite tandem battery technology to ensure the company's technological leadership.
As an enterprise that has long announced the BC route in the industry, the first 6.5G W ABC battery project in Zhuhai, a new generation of N-type ABC battery technology landmark project , has been put into operation.
3.
In the future, in order to develop the potential of ABC technology, improve the power of ABC components, reduce the cost of ABC batteries and components, and build a supply chain system with higher technology and quality. The company will continue to strengthen R & D and production collaboration with key suppliers such as silicon materials/sheets, equipment, raw and auxiliary materials.
Trina Solar
In the core technology and research progress sector, Trina Solar has focused on N-type i-TOPCon battery technology and industrialization research, HJT battery and component technology, perovskite-crystalline silicon tandem solar cells and PERC battery mass production technology.
However, elsewhere in the article, it is also noted that the company has a reserve of XBC technology.
However, as far as the current situation is concerned, " (BC battery) investment still depends on the cost performance ratio. At present, it mainly focuses on TOPCon, which is the most cost-effective technical route under the company's comprehensive consideration." Trina Solar told the media.
Atlas
battery technology, the mass production efficiency of Atlas TOPCon batteries has reached 25. The company's battery production efficiency has reached 25.
The current battery technology types of Jingao
Technology are mainly Percium battery technology and N-type Bycium + battery technology. The latest N-type Bycium + battery has the highest conversion efficiency of 25.
Among the advantages of technological innovation, Jingao said that the company's R & D center actively studies and reserves a variety of full-back contact battery, perovskite and tandem battery technologies to maintain its core competitiveness.
According to the plan, by the end of 2023, the production capacity of Jingao N-type battery will exceed 57 GW.
Dongfang Risheng
In terms of technology, the company is the first in the industry to mass-produce through its own patented 0BB battery technology, 210 ultra-thin silicon wafer technology, pure silver consumption <10mg /W and non-stress series connection technology. It further promotes the large-scale production of this series of heterojunction batteries and components.
At present, Dongfang Risheng has mass-produced G12 half-piece, 110 μm heterojunction cells: the first batch of cells of Jintan Phase II 4GW mass production line of heterojunction cells has been offline.
Zhongrun Solar
As the TOPCon production line of Chuzhou Base in Anhui and Tongshan Base in Xuzhou, Jiangsu will complete the capacity construction and reach the production capacity, it is expected that by the end of 2023, the company will be able to form more than 50GW cell production capacity.
As for the future technology, the prospectus mentioned that the company will strengthen the reserve of heterojunction, perovskite and other battery technologies, and timely promote the industrialization process of new technologies.
