"China No. 1" fills gaps in copper indium gallium selenide thin film modules
- Copper indium gallium selenide thin-film solar high-efficiency module, featuring "early rise, greedy black, and no-sleep at noon", is a pioneering achievement in the global photovoltaic field
December 26, Handan Olympic Sports Center, workers are installing blocks of dark "glass." This "glass" looks like ordinary glass, but it is not. “She†can generate electricity when it sees sunlight, and it is about 30% more efficient than conventional photovoltaic panels. This special glass is called copper indium gallium selenide film.
Today, Handan City has added a new business card: China Copper Indium Gallium Selenium Thin Film Solar Energy Efficient Module Birthplace.
On October 12 of this year, in the production workshop of Kaisheng Photovoltaic Materials Co., Ltd. in Gaoxin District, Handan City, after a piece of glass was subjected to more than 20 steps of filming, cleaning, laser etching, coating, heat treatment, efficiency testing, and product testing, When the single-armed robot accurately put the finished glass into the designated position, there was a round of applause from the factory: The first high-performance copper-indium-gallium-selenium thin-film solar module was “degradedâ€.
The copper indium gallium selenide thin-film solar energy efficient module is a groundbreaking achievement in the global photovoltaic field and marks a new stage in the transformation and development of China's photovoltaic solar energy industry. “This is a major event in the history of China’s building materials development and a milestone in the development of China's building materials industry, glass and photovoltaic industry.†At the off-line ceremony, Song Zhiping, party committee secretary and chairman of China National Building Materials Group, could not conceal their excitement. mood.
Kaisheng Copper Indium Gallium Selenium Thin Film Solar Cell Project is a strategic emerging industry project implemented by Handan City and China Building Materials Kaisheng Technology Group, with a total investment of 10 billion yuan. It plans to build 10 copper indium gallium selenide thin film solar cell production lines to form 1.5GW. Production capacity. In response, Peng Shou, party secretary and dean of the Institute for Glass Design, said that this project has created China's first place, filling China's gap in the copper indium gallium selenide thin-film module.
According to Liu Wei, deputy general manager of Kaisheng Photovoltaic Materials Co., Ltd., the copper indium gallium selenide thin-film solar cell is the most advanced thin-film solar cell in the world, with the characteristics of “early rise, greedy black, and no-sleep at noonâ€, and can not only absorb the spectrum. Wide wavelength range, good power generation stability, high conversion rate, can be widely used in various geographical environments including deserts and highlands. With a service life of up to 25 years, it is widely used in BIPV, smart agriculture, new energy vehicles, and electronic products.
"Created in China" to overcome core technologies
——The reason why the copper indium gallium selenium thin-film solar energy efficient module can lead the world is because it has taken a path of innovation of introduction, digestion, absorption, and innovation.
Kai Sheng Photovoltaic's production workshop has two football fields. The white floor, architecture, machinery, yellow markings, fences, red slogans and black pipelines are neat, with a sense of line. The reporter saw in the factory building that the huge production workshop was also 10 people.
At the end of the shop's production line stands a single-arm robot. "They" put the finished product in boxes according to different types of products. "This is the first domestic production line for copper indium gallium selenide thin film solar modules with German Industry 4.0." Liu Wei said that the production equipment imported from abroad is extremely complex, with a total value of about 1 billion yuan. As long as a network is connected, the staff can see the production and operation situation while sitting in the home. Once there are problems that need to be resolved, even if the technicians are away on business, they can all be commanded by remote control.
“Every link of the entire production line has been carefully designed by industry experts, and it has been continuously upgraded since the introduction.†Liu Xiaoyu, Technical Manager of Kaisheng Photovoltaic Materials Co., Ltd. said that the CIGS thin-film solar high-efficiency module can stay Leading the world is because we have taken a path of independent innovation that includes introduction, digestion, absorption, and innovation.
Five years ago, China Building Materials Group's affiliated Kaisheng Group acquired Avancis, the French building materials industry giant Saint-Gobain, which ranks among the world's leading manufacturers of copper indium gallium selenide thin-film solar cell technology and has created a world record for the conversion rate of photovoltaic thin film components. Although Avancis has mature technology, there is still a bottleneck in the actual conversion to production.
“In the process of introducing Avancis' new production line, Kaisheng PV paid particular attention to the problems that foreign companies had never solved in terms of production, and designed an optimization plan in advance to solve these problems one by one.†Liu Wei said, in the real sense, Having mastered the core technologies, the company has opened up China's thin-film solar photovoltaic industry chain and participated in the global new energy market competition with the "China-created" technology and brand advantages.
“Because of our technological upgrade, we have adopted a large-area glass coating technology and rapid thermal annealing technology to ensure the stability of product production and high conversion efficiency.†Liu Xiaoyu said that the application of new technologies and new materials is not only The improvement of the conversion efficiency has greatly helped the entire production process to bid farewell to the waste water and waste gas, achieving green pollution.
"Curve Road Overtaking" Striving to Become the World's Leading PV Enterprise
After completion of the project, it will become the largest and most advanced thin film solar cell R&D and manufacturing base in the country
Kaisheng Photovoltaic has the most advanced production lines and world-class products in the industry, which makes many people mistakenly believe that the company is "old" in the industry. And this is not the case. Kaisheng Photovoltaics, as a new army of photovoltaics, relies on innovation to realize “curve passing†and leads domestic counterparts.
“The company has only been established for two years. The 300MW production line that has already been put into production is the first phase of the project, and it is expected to achieve a sales income of over 1.2 billion yuan and a profit tax exceeding 300 million yuan. After the project is completed, it will become the largest and most technologically advanced in the country. Thin film solar cell R&D and manufacturing base." said Liu Ye.
Liu Xiaoyu said that the successful construction of the project has achieved the domesticization of thin film solar modules for copper, indium gallium selenide and thin-film, opened up the entire thin-film solar module industry chain in China, built China's largest thin-film solar photovoltaic base, and established a core for new energy development. Significance.
"The commissioning of the project can drive the development of the entire industry." In Peng Shou's opinion, in recent years, the Glass Industry Design Institute is committed to the development of new "four new" industries in glass, new materials, new energy, and new equipment. The National Science and Technology Progress Award was awarded three times during the year. More than 20 ultra-thin information glass production lines built by the company have not only reduced a great deal of costs for the downstream industries, but also achieved a leap from “walking†to “leadership†internationally.
As the Kaisheng Group has a complete upstream and downstream companies, it is the world leader in the glass industry, which greatly reduces the cost of raw materials for copper-indium-gallium-selenide thin-film solar cells and can create an “upgraded version†of top-notch technologies at a lower cost. The copper-indium-gallium-selenium thin-film solar cells created by “China†are more competitive on the world stage.
Xu Genbao, General Manager of Kaisheng Photovoltaic Materials Co., Ltd., said that the company is keeping a close eye on the world record of photovoltaic conversion rate and has already started scientific research and strived for one to two years to achieve 20% conversion efficiency and create a new world. Record. The company will endeavor to make the world's first copper-indium-gallium-selenium thin-film solar cells and lead the development of the world's photovoltaic industry.
