Coal can generate electricity, water can generate electricity, and solar energy can generate electricity, but the former two are non-renewable resources, while the latter can be “inexhaustible for children and grandchildrenâ€, which shows that it has great potential for application in human production and life. . Solar energy can be converted into heat, solar water heaters have brought convenience to countless people; solar energy can also be converted into electricity, "solar energy taken during the day, converted into electricity stored in the battery, and then let the electricity 'release' out at night. The solar energy can be used to make the lights bright for four or five days, even if it is cloudy and cloudy. Experts say that this is the advantage of the “photovoltaic industryâ€.
The "photovoltaic industry" that converts solar energy into electric energy, the most widely used carrier is called crystalline silicon photocell, but the high-purity crystalline silicon purification technology has been monopolized by a few developed countries. The import price is expensive, and the domestic production of crystalline silicon purification technology It is of great significance. A few days ago, the reporter learned from relevant parties in Shaoxing, Zhejiang, that Dr. Li Qiao, who returned to China to start a business, has successfully developed a process for purifying crystalline silicon from metallurgical silicon through technological innovation. With this process, crystalline silicon can be purified to more than 99.9999%. Breaking the technical bottleneck of the severely limited development of the domestic photovoltaic industry. This year, two companies in Zhejiang joined Dr. Li Qiao, invested more than 30 million yuan to establish "Bijing Technology" company, and launched a technical breakthrough in this, and finally achieved a major breakthrough. At present, the company's photovoltaic industry crystalline silicon project has been included in the city's "50 key industrial construction projects" this year.
Experts said that the basic principle of solar power generation is to use solar panels made of high-purity silicon and other semiconductor materials to directly convert solar energy into electrical energy, because it accounts for about 80% of the cost of solar cell manufacturing, so silicon materials Known as the "throat" of the photovoltaic industry. In the past, the international silicon purification production technology was mainly controlled by 8 companies including Tokuyama, Mitsubishi, Hemlock, MEMC, and Wacker in Germany. They have a special monopoly. They jointly prohibit technology transfer to other countries. For decades, other countries There is no door to buy, and China is no exception. The “throat†of the photovoltaic industry has always been “squeaky†and can’t breathe. According to reports, the current international silicon purification technology method is mainly Siemens, Dr. Li Qiao successfully developed the technical process is completely different from this, he first used physical methods to directly extract from metallurgical silicon into solar high-purity silicon single crystal, not only realized Low cost, high output and no pollution, and the purity of silicon material after large-scale production still maintains a high purity of 99.9999% or more. "At present, we have entered the stage of substantial small-scale trial production, and we are undergoing process optimization and equipment improvement, and preparing for expansion before production." Li Qiao said.
It’s not spring, but the flowers are all over the spring. Seeing the advantages of developing the photovoltaic industry, this year, Zhejiang Shangyu has been engaged in a large number of traditional industries such as electromechanical, chemical, printing and dyeing, such as Longbai, Sunshine, Ruiqi, Tianwaitian, Wolong, etc., and they have turned their eyes to this " Green industry." “Traditional industry profits are getting thinner and thinner, resources and environmental constraints are becoming more and more conspicuous. According to the requirements of energy conservation and emission reduction, everyone is looking for new space for investment.†Zhu Bagen, chairman of Longbai Group, which started from printing and dyeing textiles, said in a concise manner. Mystery. According to statistics from the relevant departments of Zhejiang, there are currently 1 billion yuan of private capital flowing to the photovoltaic industry in Shangyu.
It is reported that Longbai Group, which was established in 1993, is a comprehensive export-oriented national large-scale enterprise integrating weaving, printing and dyeing and chemical fiber. The company has advanced production lines of weaving, printing and dyeing and chemical fiber imported from Germany, Japan and Italy. And has established an effective computer design control system, mainly producing large jacquard satin, cotton silk dyeing and various dyed fabrics, colored polyester staple fibers, jacquard fabrics, towels, ribbons and various yarns, silk bleaching and dyeing products, products are not only popular The domestic market is also exported to Japan, South Korea, Singapore, Malaysia, Australia and the Middle East, Africa and Europe and the United States and other countries and regions. This time, Longbai Group invested more than 800 million yuan in “new spaceâ€, and entered the photovoltaic industry, using the upstream products provided by “Bijing Technology†to produce the raw materials needed for crystalline silicon photovoltaic cells—solar silicon wafers and battery chips. The “Longbo Photovoltaic†Phase I project is expected to be completed and put into operation in the first half of next year. After the completion of the project, the annual output value is expected to reach more than 2 billion yuan, which will far exceed the current annual output value of Longbai Group's traditional business of 500 million.
In the research and development of photovoltaic terminal products, Zhejiang Sunshine Group, one of the world's largest manufacturers of energy-saving lamps, has introduced a doctoral team dedicated to the research and development of solar lighting and solar LED and OLED light source technologies. Previously, they jointly invested in research and development of low-power, high-brightness lamps that can be used in solar cell photovoltaics, which have been jointly developed by Xi'an Jiaotong University. Xu Guorong, general manager of Sunshine Group, said with a smile: the medium- and long-term development plan for renewable energy released by the state.
There is a prediction that by 2020, the consumption of renewable energy including solar energy will reach 15% of China's total energy consumption. The prospect of photovoltaic industry is limitless. The driving effect of photovoltaic industry projects has changed our traditional economic restructuring. thinking. Fu Yawen, vice chairman of the Shangyu CPPCC, believes that a place that combines new energy and new materials to carry out independent innovation and key development, and masters a certain technology with super core competitiveness, combined with the existing industrial base, It may pull out a new high-tech industrial chain of its own. Chen Jian, deputy mayor of Shangyu City, said, “What makes us excited is that under the guidance of photovoltaic high-purity silicon project, a solar silicon material, battery, power generation and application The complete industrial chain will be expected to be generated in the captain. â€
The investment increment focuses on industrial innovation. In order to promote the adjustment and upgrading of industrial structure, Zhejiang Shangyu has issued a special policy. By formulating energy conservation and emission reduction targets, on the one hand, it encourages relevant enterprises to develop circular economy and clean production to replace traditional industries. On the other hand, through the development of high-tech industries, Incrementally dilute the proportion of traditional industries in the entire industrial economy, further optimize the industrial structure, and focus on supporting demonstration and driving industries and projects, including the photovoltaic industry, and achieve certain breakthroughs.
