Leshan: The rise and flying of 100 billion "China Green Silicon Valley"

At 21:18:00 on August 8, 2022, all people pay attention to ——

The crystalline silicon light film made by "Leshan" absorbs the first ray of sunshine in Jinding, Emeishan, and transformed into a "fire species" generated by electricity.

Global crystal silicon looks at China, Chinese crystal silicon looks at Sichuan, and "China Green Silicon Valley" is in Leshan.

China Green Silicon Valley

On January 9, 2000, the national key scientific and technological innovation project undertaken by Emei Semiconductor Materials Factory in Leshan City, Sichuan Province, the first annual output of 100 -ton polysilicon industrial test demonstration line through the national identification.

In 2021, the national polysilicon output was about 500,000 tons, accounting for more than 70%of the global output, and the output of Leshan polysilicon in Sichuan accounted for approximately 13%of the national output. It is expected that in the next two years, about half of the nationwide polycrystalline silicon capacity comes from "Sichuan".

Sichuan is becoming the original point of Chinese polysilicon and the commanding heights of the future.

In recent years, the Sichuan Provincial Party Committee and the Provincial Government have given Leshan an important mission to the construction of "China Green Silicon Valley". With the goal of "carbon peak, carbon neutral", Leshan City uses "crystal silicon photovoltaic" as the "number one project" for Leshan. The long -term planning of the urban industry development.

Anchoring and building the core area of ​​"China Green Silicon Valley", Leshan City Wutongqiao District is vigorously implemented the industrial park empowering and upgrading operations, strive to create a provincial economic development zone, continuously build strong industrial carriers, plant the foundation of thick planting industries, and promote crystal silicon photovoltaic photovoltaics The industry realizes the circulation of the entire industry chain, accurately develops a strong chain supplementary chain extension, and attracts a large number of leading enterprises, cutting -edge technologies, and high -end talents to gather Leshan and accelerate the growth of industrial clusters.

Half of the global crystal silicon photovoltaic fields settled in Leshan, the world's largest silicon material production base rose in Leshan, and the world's most advanced solar -grade crystalline silicon manufacturing core technology was born in Leshan.

On November 5, 2020, Leshan was awarded the title of "Green Silicon Valley" by the China Nonferrous Metal Industry Association.

At present, "China Green Silicon Valley" has 15 crystal silicon photovoltaic and supporting projects, with a total investment of 60 billion yuan. 113,000 tons of high -pure crystalline silicon, 20,000 tons of granular silicon, 55GW single crystal pull rod, and 17GW silicon wafer production capacity, high -pure crystal silicon production ranks first in the world. During this year, the output value of the crystal silicon photovoltaic industry will exceed 60 billion yuan, driving the total output value of Wutongqiao District's industrial output value sprint 100 billion yuan.

Phoenix Nirvana -The "Star Fire" of Liaoyuan in the rebirth of the fire

Entering the digital experience center of Sichuan Yongxiang Co., Ltd., Wutongqiao District, Leshan City, in the center of the front wall of the hall, a "Phoenix" is reborn and fluttering.

"China Green Silicon Valley" logo

Broken mottled and bright wings and phoenix tails, the piano that is struggling to be upward, the blue -green bottoming phoenix ... In the golden sunlight, a "crystal" phoenix flies in the air, and the light "covers" the future.

The chip and the sun, green and environmental protection, crushing and flying ... as the "silicon dream" journey that lasted more than 40 years of Leshan for more than 40 years, in several innovative pains, the fire was reborn, and the phoenix Nirvana.

From 1964, the Ministry of Metallurgy's decision to move Emei to build a non -ferrous metal factory, to the first polysilicon production workshop in July of the following year, and comprehensively tried and put into operation in October. The level of international advanced products.

However, the disparity of the development of industrial technology has led China to lose its right to speak. At the end of the last century, domestic polysilicon output was less than 100 tons, accounting for less than 0.40%of the world's total output, and domestic gaps reached more than 95%.

The United States, Germany, Japan and other countries have almost monopolized global polysilicon production. my country's information industry and photovoltaic industry have to be maintained by purchasing foreign polysilicon and single crystal silicon remnants. Low quality, high cost, subject to people, the entire industry is passive and unstable.

On January 9, 2000, a milestone in the history of Chinese polycrystalline silicon ushered in a milestone. The Emei Semiconductor Material Factory has 100 tons/year production capacity. The first domestic "improved Siemens method" polysilicon national key test demonstration production line with independent intellectual property rights has reached the international advanced level through national identification and acceptance. It marks that China's polysilicon breaks the monopoly of foreign technology.

In 2008, Sichuan Yongxiang Co., Ltd. was completed and put into operation at an annual output of 1,000 tons of polysilicon projects, becoming China's largest polysilicon production enterprise.

At the same time, the national silicon material development and by -product use of high -tech industrialization bases have also settled in Leshan.

Leshan- "Silicon Valley in the West", his reputation rises.

However, from September 2008 to around 2011, it was affected by multiple factors such as the financial crisis and the "double anti" in Europe and the United States. The price of polysilicon fell from 3 million yuan per ton to 400,000 yuan. The development of China's polysilicon industry was seriously affected and difficult. In Leshan, there were only one Sichuan Yongxiang in the heyday.

Facing the sudden winter of the industry, the survival crisis forced enterprises to practice internal skills.

After 4 technical reforms and upgrading, the "Yongxiang Law" with independent intellectual property rights - "Fourth Generation Yongxiang Law" (including core technologies such as large -scale distillation energy saving, cold hydrogenation, and anti -dismissal) All silicon is converted into the production of raw orthosiline silicon, which turns waste into treasure, improves quality and reduce consumption, and breaks through technical barriers.

Sichuan Yongxiang high -pure crystal silicon material

Today, Yongxiang's technology is upgraded to the "Sixth Generation Yongxiang Law". Product quality, production costs, and process technology indicators are comprehensively leading. Chinese intelligent manufacturing. " "Next, the company will carry out a new round of technology upgrade, integrate the currently most advanced process technology into one to form the" seventh generation Yongxiang Law ". Compared with the previous generation, the cost decreases by 5%-10%. Yongxiang Energy Technology, which adopts the "Seventh Generation of Yongxiang Law", will also start construction in the near future. " 230,000 tons (including Yunnan and Inner Mongolia base companies), in 2023, will reach 350,000 tons.

Sichuan Yongxiang has grown into an industry benchmark for the development of clean energy and creating high -pure crystalline silicon and photovoltaic industries. It is moving towards the unremitting struggle of world -class enterprises and world -class clean energy companies that create high -pure crystalline silicon.

A single spark can start a prairie fire. The support of national policy, the support of the government environment, the leadership of the industry, the gathering of investment promotion, the extension of the industrial chain ...

From "Western Silicon Valley" to "China Green Silicon Valley" successfully upgraded, Leshan Crystal Silicon Photovoltaic Industry has gathered.

Rise of Gathering -the "Chain" of a green cycle in the innovation construction

The salt continued for thousands of years, and the bridge was all five continents.

A few days ago, the reporter walked into a new industrial base in 10 square kilometers of Wutongqiao District, Leshan City, Sichuan. I saw the hillside change park and farmers become workers -many crystal silicon photovoltaic industrial projects in full swing, you chase me, the machine roars of machines everywhere in the production workshop, happy Essence

He came to Yongxiang New Energy Company, known as the "garden -style factory", with green grass and factories. Entering the distillery workshop, various automation equipment operates efficiently, the production line is full of load operation, and the high pure crystal silicon produced from the factory is continuously transferred to downstream enterprises across the country.

"The total investment of the 12GW rod and the cutter project of Leshan Peking Express was 4.1 billion yuan. With the strong assistance of Leshan, Wutongqiao Government and the local management committee, it took 83 days from the land construction to the ignition. Speed ​​'refreshed the industry construction records. All in June this year have reached the conditions of production. "Zhang Peng, executive deputy general manager of Leshan Peking Transport, introduced," The research and development of CCZ continuous pull -up process can make the vertical resistivity of single crystal silicon wafers. The range is more concentrated, providing better products for the improvement of battery conversion efficiency. "

Zhang Peng also revealed that at present, the 22GW pull rod, cutter, and section project of Leshan Jingong Phase II are actively handling relevant procedures. Construction will be started after the construction conditions are available.

In Leshan, the development of "China Green Silicon Valley" is evident.

At the time of the Sichuan photovoltaic industry cluster, people even saw that Leshan made the resource utilization and green cycle.

"All the" Leshan -made 'crystal silicon photovoltaic enterprises use hydropower, which truly realizes the ‘new energy' by‘ clean energy ’.” Said the assistant general manager of Sichuan Yongxiang Co., Ltd., Shi Changhong.

Enterprises seize opportunities and catch up with than super; the local government has further advanced to build "China Green Silicon Valley" as the "number one project".

"Enterprise management in the wall, government management of the wall." Leshan raised the city's power, gathered the city's wisdom, and the same frequency of resonating the industrial development of fertile soil.

In recent years, Wutongqiao District has vigorously implemented the industrial park to empower the upgrade operation. 5 110KV substations and 4 220kV power stations have been established and launched. Construction of seat 220kV substation. The first phase of the industrial water supply plant, the industrial solid waste yard and other basic supporting facilities were put into use. Simultaneously promoting the construction of 6 parks, the three -dimensional transportation network of enterprises and enterprises, and the internal and inside -in -situ interaction accelerated.

Make good use of the policy "rainy rain". Leshan implemented the province's "hydropower consumption demonstration", "precise support for electricity prices" and other beneficiary enterprises and enterprises, formulated and implemented "22 photovoltaic", "" Ten hard measures for "Chinese Green Silicon Valley" talents, "30 articles of investment promotion", etc. Give support in many aspects such as factor protection and build a good industrial ecology.

Be a good company "waiter". Leshan optimize the business environment, implement the "weekly monitoring, monthly scheduling, and season inventory" mechanism, establish a "red and black list" system for project progress, implement the entire process of pocket insurance, project commissioner to follow up, and on -site office mechanisms to promote the project to accelerate the project to accelerate Completed and put into production. The Yongxiang New Energy Project and Leshan High -testing Project were put into operation in the year, and the Jingke Energy Project was only 100 days started to start production.

At the same time, activate the industrial chain through "outer citation". Leshan aims at polysilicon and photovoltaic "silicon material -silicon wafers -battery sheet -battery component -solar photovoltaic power plant" full industry chain. Investigate more than 100 crystal silicon photovoltaic enterprises such as crystal energy, Poly GCL, and Tongwei Group.

Continue to amplify the "magnetic effect" and promote the development of the crystal silicon photovoltaic industry. The crystalline silicon photovoltaic industry has realized the "three breakthroughs" from scattered layout to centralized film, industrial chain from silicon material to slicing, and electronic -grade polysilicon projects from scratch.

"Building the nest attracted the phoenix." Five of the top ten photovoltaic companies in the world have settled and participated in Leshan, Leshan Crystal Silicon photovoltaic industry has advanced to the "first square" of global silicon materials.

Struggle for the economy and construction. From January to June, the city's high-pure crystal silicon output was 69,600 tons, the rod is 14.01 Gava, and the slices were 634 million pieces, achieving an output value of 26.66 billion yuan, an increase of 382.2%year-on-year. Leshan- "China Green Silicon Valley" has risen, and it has a better color!

Flying on the momentum -the "target" of 100 billion Silicon Valley under the grand blueprint

Expand the "Fourteenth Five -Year Plan" of Leshan City and the development of the development of the crystal silicon photovoltaic industry during the future. You can see a clear development trajectory-
