Longi: The world's largest photovoltaic cell production base with the highest capacity has been put into production
Cost reduction and efficiency improvement and technological innovation are the theme of the development of the domestic photovoltaic industry. Photovoltaic enterprises compete to offer more efficient battery products. Improving conversion efficiency will still be the main direction of the upstream and downstream photovoltaic industry chain.
Companies for the figure
As the largest solar technology company in the world, Longji Green Energy (share price: 45.89 yuan, market value: 347.9 billion yuan) is a typical technology-driven company. It has always adhered to the principle of "not leading or expanding production", achieved breakthroughs in battery efficiency many times, and constantly broke world records.
Zhong Baoshen, chairman of Longji Green Energy, also called for technological innovation to be the driving force for the long-term development of enterprises, and the photovoltaic industry should return to the main track of battery efficiency improvement.
On September 28, the high-efficiency single crystal battery project of Jinghe New Town, Longji Lvneng Xixian New Area, was officially put into production, which is also the largest single photovoltaic cell production base with the highest capacity in the world. On the same day, the Longji Academia Research Institute headquarters project was also finalized in Jinghe New City.
The layout of Longi Green energy is bound to have a profound impact on the technological innovation of the industry and the development of the new energy industry. In this regard, the reporter dialogue Longji green chairman Zhong Baoshen.
The world's largest monomer, the highest capacity
Reviewing the development trend of photovoltaic industry, technological progress is the core factor driving the continuous improvement of battery conversion efficiency.
Fifteen years ago, the cost of monocrystalline silicon was so high that until 2004, the market share of monocrystalline silicon was still less than 5%. Longji Green can continuously reduce the manufacturing cost of monocrystalline silicon and improve the conversion efficiency of photovoltaic power generation, so that the market share of monocrystalline silicon has reached more than 90%, becoming the mainstream of the market.
Longi single-handedly led the development of single crystal revolution, pushed the photovoltaic power generation into the road of cost reduction, and changed the pattern of the whole world photovoltaic industry. Since then, this technological change has been in the DNA of longi development.
"The core of photovoltaic is the continuous reduction of the cost of kilowatt-hour electricity and the improvement of the power generation efficiency of batteries, and Longji has always spared no effort in this regard," Zhong said.
In 2019, Longi's single-crystal double-sided PERC cell frontal conversion efficiency reached 24.06%, breaking the bottleneck of 24% and setting a world record.
In June 2020, Longi Battery R&D Center announced the world's highest conversion efficiency of 25.21% certified by the world's recognized authoritative testing institutions, realizing the overall leadership of new solar cell technology in the field of N-type TOPCon batteries.
Since then, Longi in PERC, TOPCon, HJT technology line "full flowering". In 2021 alone, Longi has broken seven world records for photovoltaic cell conversion efficiency in different technological routes. The conversion efficiency of N-type TOPCon, P-type TOPCon and N-type HJT cells was increased to 25.21%, 25.19% and 26.30%, respectively.
On the production of high efficiency single crystal battery project in Jinghe New City, Zhong Baoshen told "Picture" reporters that the production of high efficiency single crystal battery project is Jinghe New City Longji green photovoltaic industrial Park, one of the three major components of the project, but also the world's largest monomer, the highest capacity of photovoltaic cell production base.
According to Zhong Baoshen, the above project covers an area of 872 mu. The products apply the latest technology of Longji Green Energy. It is expected that the annual output of 15 gigawatts will be achieved after the production is completed next year, and the annual output value will reach 30 billion yuan, and 8,000 people will be employed.
The project put into production, no doubt, have far-reaching significance to the promotion of photovoltaic industry conversion efficiency, Zhong Baoshen also calls for photovoltaic industry should focus on running the reliability of the new energy assets of more than 25 years, to ensure its guaranteed in the whole life cycle, suggest return battery efficiency of main circuit, strengthen the battery r&d of new material, new technology, by authors of scientific and technological innovation efficiency.
'Photovoltaic Brain' for High-efficiency batteries
For a long time, Longji Green Energy has always maintained strong investment in R&D. Data show that it is the largest enterprise in the global photovoltaic industry with R&D investment accounting for about 5% of its revenue. Since its listing in 2012, Longji Green Energy has invested more than 13 billion yuan in R&D.
Therefore, in addition to the production of the high-efficiency single crystal battery project, Longji also signed an investment agreement with Jinghe New Town for the Academia Sinica Headquarters project.
Zhong Baoshen said that the project is an important carrier for Longji Green to carry out photovoltaic industry research and development, as well as another important part of its photovoltaic industrial park, which will have world-class research and development level after completion. It is also known as the "photovoltaic brain" because its construction goal is to provide R&D technical support and patent reserve for the industrialization of next-generation high-efficiency batteries.
According to public information, Longji Academia Research Institute Headquarters project was launched in Jinghe New Town in 2021, covering an area of 410 mu. The construction content is a high-efficiency single-crystal battery research and development center and an annual output of 2GW single-crystal battery pilot production line. It is mainly engaged in the scientific and technological research and development, pilot test and public testing of new technologies in the photovoltaic industry. Research and development direction includes new battery and component technology, new material technology, hydrogen energy application technology, high-end equipment technology, biomass technology, etc. Committed to the hardware conditions, R & D team, R & D results, R & D demonstration and other aspects to create a world-class R & D platform.
According to Zhong Baoshen, Longji Green Energy Photovoltaic Industrial Park is currently under construction, and about 4,000 high-end scientific research talents will be introduced after the institute is officially put into operation, of which more than 85% are with master's and doctorate degrees, and about 20% are the top talents in the field of new energy related research.
In fact, Longji Academia Sinica is not only supporting the research of high-efficiency single-crystal batteries, but also providing technical reserves and solutions for Lonji's new track hydrogen energy, so as to promote sustainable development of the enterprise.
Zhong Baoshen said the project will effectively support the central research institute headquarters longji form "green electricity" + "green hydrogen" products and solutions capabilities, continuous build monocrystalline silicon slice, battery components, industrial and commercial distributed solutions, green energy solution, the hydrogen equipment five business sectors, enterprises can also boost energy revolution, to build "zero carbon" earth "green earth".
Local hundred-billion-level photovoltaic clusters
Longji Green Energy is a world-renowned monocrystalline silicon manufacturing enterprise, the largest solar energy technology company in the world, and also a local enterprise in Xi 'an. Its main manufacturing projects and R&D supporting projects are of far-reaching significance to the local development of manufacturing industry.
"The enterprise mission of Longji Green Energy is to 'make good use of the sun's rays and create a green energy world', which coincides with the development concept of Jinghe New City in Xixian New Area, which takes' South Mountain, North water, smart Jinghe River 'as the city brand." When talking about the cooperation with Jinghe New City, Zhong Baoshen told reporters.
