On January 10, Longji Green Energy issued a heavy announcement that it intends to change the " Xixian Leye 15GW High Efficiency Single Crystal Battery Project " to " Xixian Leye 29 GW High Efficiency Single Crystal Battery Project ". The fund raised by the original project of 4.77 billion yuan was also changed to the new project of Xixian Leye with an annual output of 29 GW high-efficiency monocrystalline batteries . According to
several additional layout HPBC battery production line
announcements, the total investment of Longji Lvneng Xixianleye's annual output of 29 GW high-efficiency monocrystalline battery project is 7.040 billion yuan, and the battery technology of the above project will be introduced into the company's self-developed & nbsp; HPBC high efficiency battery technology, forming an annual production capacity target of 29 GW monocrystalline high efficiency batteries.
The project is expected to be fully operational in September 2023.
This is another heavy increase since the company officially disclosed HPBC high-efficiency monocrystalline batteries in January 2022. In January
2022, Longji Green Energy HPBC battery entered the photovoltaic industry for the first time. On January 24,
2022, Longji Green Energy announced that the original 2GW monocrystalline battery project in Taizhou Longji Battery Factory was transformed into eight HPBC high-efficiency monocrystalline battery production lines, forming a 4GW battery production line. Longji Green Energy HPBC Battery was born. One year
later, Longji Green Energy once again announced the doubling of the HPBC battery project, which also shows the confidence and expectation of this battery technology.
Longji Green Energy mentioned the reasons for the change, in view of the company's independent research and development of HPBC high-efficiency battery technology, large-scale commercial conditions have matured.
Longji Green Energy HPBC Battery Project has entered the stage of mass production.
In the semi-annual report of 2022, Longji Green Energy said that in terms of battery components, the company has developed and reserved a variety of new battery component technologies, seeking breakthroughs in the direction of new high-efficiency battery technologies such as n-type TOPCon, p-type TOPCon, n-type HJT and p-type HJT. It has creatively developed HPBC structural batteries (Hybrid Passivated Back Contact), and continuously promoted the mass production and transformation of new high-efficiency batteries and components in terms of high cost performance and commercialization. We are ready to create differentiated products and build long-term competitive advantages .
HPBC is the abbreviation of composite passivation back contact battery , which is a new generation of high efficiency battery technology characterized by no grid line on the front of the battery. HPBC battery technology has been developed by Longji Green Energy Battery Scientists for many years and has finally been commercialized.
According to Longji Green Energy, the product has the advantages of beautiful appearance, high conversion efficiency, good weak light response, low temperature coefficient and high reliability , and can be widely used in roof, ground power station and other scenarios.
In addition, stable conversion efficiency is its most eye-catching advantage. Who will be the next leader in the
photovoltaic cell industry?
In the photovoltaic industry chain, the cell is the core link of the industry. Under the core driving force of "reducing cost and increasing efficiency", many battery manufacturers continue to pursue higher power generation efficiency and yield at lower cost, so it is also the most critical link of technological innovation, and technological innovation and iteration are very rapid.
In 2022, the efficiency of N-type photovoltaic cells has been continuously refreshed, and many leading manufacturers have announced that their R & D conversion efficiency of monocrystalline silicon cells has exceeded 26%, and the mass production efficiency has exceeded 25%.
This time, Longji Green Energy said that the production efficiency of the standard version of HPBC battery exceeded 25% , and the efficiency of the PRO version with hydrogen passivation technology could exceed 25.3% . According to Longji Green Energy, the efficiency of the product can be more than 26.5% in the future, and the component efficiency can be nearly 24% . Therefore, it has attracted the attention of the industry.
At the same time, in recent years, with the efficiency of P-type battery technology gradually entering a bottleneck period, higher conversion efficiency of N-type silicon based TOPCon, heterojunction (HJT) and other high-efficiency batteries are highly expected. It has been continuously concerned by many photovoltaic players and added to the layout.
On January 10, Shijing Science and Technology, an environmental protection enterprise, announced that it planned to invest 11.2 billion yuan to build a cross-border project with an annual output of 24 GW high-efficiency N-type single crystal TOPCon solar cells. The investment plan disclosed
by Ovi Communications on January 2, 2023 shows that the company intends to form a joint venture with Entropy (Shanghai) Energy Technology Co., Ltd. to invest in the construction of 5G W high-efficiency HJT solar cell and component projects. On December 23,
2022, the photovoltaic giant Haiyuan Composite Material planned to invest 8 billion yuan in the construction of 5G W HJT ultra-high efficiency photovoltaic cells and 3GW high-efficiency photovoltaic modules for the 10G W TOPCon high-efficiency photovoltaic cell project. On December 10, 2022
, Xiexin Integration disclosed its non-public offering plan to raise 6 billion yuan for Wuhu Xiexin 20GW (Phase II 10GW) TOPCon high-efficiency cell manufacturing project.
……
According to agency statistics, only in 2022, TOP10 component companies such as Jingao, Tianhe, Jingke and Zhengtai have launched GW TOPCon mass production. Heterojunction (HJT) has also attracted many new entrants by virtue of its short process and clear cost reduction route.
In addition, as the third generation of solar cell technology, perovskite cell technology has emerged as an innovative direction of the new generation of solar cell technology with subversive high conversion efficiency, which is highly expected.
Nowadays, the photovoltaic cell industry is flourishing and contending. In the pursuit of each other, technology is constantly breaking through, innovating and iterating, thus achieving faster development of the industry.
However, different technologies have different technological advantages and shortcomings, each has its own merits, but also has completely different industrial chain supporting resources, who becomes the next leader, or even subversive, will cause great changes in the industrial structure of the industry.
