Low carbon calls for the maturity of the new energy photovoltaic industry

the photovoltaic industry has developed rapidly, and the industrial scale, economy and marketization degree have increased year by year. With the breakthrough of thin-film battery technology and the gradual realization of industrialization, the cost of photovoltaic power generation will be reduced to the level that can compete with conventional fossil energy power in a very short time, so as to accelerate the transformation from supplementary and alternative energy to major and mainstream energy

on the eve of the United Nations Climate Change Conference in Copenhagen, the executive meeting of the State Council made an important decision: by 2020, the carbon dioxide emission per unit of GDP will be reduced by 40% - 45% compared with 2005; Non fossil energy accounts for about 15% of primary energy consumption. Recently, Zhang Guobao, director of the national energy administration, proposed to start immediately to ensure that the goal of "non fossil energy accounting for about 15% of primary energy consumption" will be achieved by 2020. Insiders believe that this means that China's low-carbon economy era has arrived, and the new energy industry will enter a new stage of development

Li Junfeng, deputy director of the Energy Research Institute of the national development and Reform Commission, pointed out that in the 21st century, countries all over the world regard the development and utilization of new energy as an important part of their energy strategies for the security of energy supply and the response to climate change, put forward clear new energy development goals, formulate laws and policies to encourage the development of new energy, and promote the rapid development of the new energy industry

it is reported that driven by the world photovoltaic market, China's photovoltaic export value in 2008 was nearly 150billion yuan, accounting for 1/3 of the world's output, which is the sum of Germany and Japan, leaping to the first place in the world. In just a few years, China's photovoltaic industry has formed a number of international brands, such as Wuxi Suntech, Baoding Yingli, Changzhou Trinasolar, Jiangsu Saiwei, Hebei Jingao, and has rapidly become a strategic emerging industry with independent brands, independent intellectual property rights, independent innovation capabilities, and international competitiveness

the inevitable choice of low carbon

due to the impact of climate change on the earth's ecology, such as the continuous rise of global temperature, the increase of extreme climate phenomena, the frequent occurrence of natural disasters, etc., have threatened the survival and safety of mankind. Reducing carbon dioxide emissions, slowing down climate warming, and maintaining the ecological environment for human common survival have become the direction of joint efforts at all levels of society. In this context, people have gradually formed a consensus on the concept of low-carbon economy. The main technological choice for low-carbon development is to vigorously develop low-carbon energy technologies represented by wind power and solar energy, in addition to changing the mode of economic development and greatly improving energy efficiency

Li Junfeng pointed out that in the past 30 years of development, the photovoltaic industry has accumulated rich experience and has become a mature industry, and the cost is declining. Whether optimistic or conservative estimates, around 2020, the cost of photovoltaic power generation can be controlled below 1 yuan per kilowatt hour, and has the ability of large-scale development. Due to technological progress, the pollution in the production process of photovoltaic cells can be completely controlled, and the energy consumption is constantly declining. At present, a considerable number of resource-based cities in China are facing transformation difficulties to control below 50g, which is only about 5% of coal-fired power generation

the park is in action

the first batch of 1000 high-efficiency color solar cell modules produced by Hunan Shenzhou optoelectronics were packed and transported to Shanghai on February 2, 2009. These products were then laid on the side wall of the viewing platform of the China Pavilion of the Shanghai WorldExpo. It is reported that the high-efficiency color solar power generation system jointly developed by Shenzhou optoelectronics and the scientific research team in Taiwan is an important achievement of large-scale exchanges and cooperation between Changsha and Taiwan

the "annual output of 200MW high-efficiency crystalline silicon solar cells and application products" project of Shenzhou optoelectronics is a project contacted by Changsha Taiwan Affairs Office in the "two help and two promotion" activities of Changsha high tech Zone. In March, 2009, Zhaofeng, chief engineer of Shenzhou optoelectronics, established contacts with photovoltaic research institutions and enterprises in Taiwan, such as Delta Electronics, which led to the cooperation of the project with Taiwan lofook company in the production of high-efficiency color solar cells, and successfully won the bid to produce color solar cell modules for the China Pavilion of Shanghai WorldExpo

at present, the photovoltaic industry in Changsha high tech Zone is rising like a rising sun. The polysilicon purification technology introduced in its leading products and technologies is relatively mature. The successful preparation and production of solar grade silicon such as silicon ingot and silicon rod "slurry polyethylene catalyst amplification preparation and industrial utilization experiment" has formed a certain industrial scale, with strong solar cell manufacturing capacity and large output. The weak link of the industrial chain lies in the raw materials of solar silicon, solar modules, module packaging, terminal supporting application products and other parts, and the upstream and downstream supporting facilities are missing. Changsha high tech Zone plans to achieve an output value of 50billion yuan of solar photovoltaic industry by 2015, with a planned construction area of 4 square kilometers. Establish a 2-square-kilometer Hunan photovoltaic industry base integrating R & D and production, based on Hunan's relatively mature technology and equipment advantages in solar cell production, speed up the breakthrough of the bottleneck of solar silicon materials, rely on the equipment R & D and production advantages of CLP 48 and other enterprises, coordinate and integrate the silicon production of Yiyang and Zhuzhou, and coordinate the development of Hunan photovoltaic industry, Form a complete industrial chain of silicon ore - industrial silicon - polysilicon (monocrystalline silicon) - silicon wafer - battery wafer - battery module - solar energy application products and photovoltaic power generation systems, take the road of industrial cluster development, and build a solar photovoltaic industrial base with the most level, scale and influence in China

it was learned that in recent years, with the support of the national policy of vigorously promoting the development of new energy industry, the photovoltaic and solar energy industries in Baoding high tech Zone and Wuhan East Lake high tech Zone have achieved large-scale development. In addition, Jiangxi Province has also seized the opportunity to take advantage of the resource advantage of having the largest reserves of powdered quartz in the country, and has introduced various measures to ensure the development of the photovoltaic industry. At present, a large number of upstream and downstream projects of the photovoltaic industry have rapidly gathered in Jiangxi and become an important photovoltaic industry base in China

enterprises are at the forefront

on December 15, 2009, the 3000 ton polysilicon project of phase I of 69 silicon industry under Yingli group, a domestic photovoltaic enterprise, was successfully put into trial production. Miao Liansheng, chairman of Yingli group, said that the 69 silicon industry mainly adopts the new silane process, which greatly reduces energy consumption and pollution. "At present, the technology adopted by Liujiu silicon industry is the first in China, and the total investment of Liujiu silicon industry is about 12billion yuan." Zhang Yuehe, the general manager of the company, predicts that after the first phase of the 69 silicon industry is put into operation, it will achieve an annual output value of 1.2 billion yuan. Ma Xuelu, Chief Strategic Officer of Yingli group, said that the successful commissioning of the 3000 ton polysilicon project marks that Yingli group has the most complete and optimized photovoltaic industry chain in the world

"as the leader of the photovoltaic industry in Baoding and the only solar cell manufacturer in the whole industry chain in China, Yingli group has experienced the process of starting, groping and rapid development. In just a few years, it has gone through the process that similar foreign enterprises need 20 years." Li Qian, the acting mayor of Baoding, believes that the successful trial production of Yingli group's 1GW battery modules and the 69 silicon industry has greatly improved Yingli's comprehensive production capacity, which is of great significance for leading the domestic photovoltaic industry to expand production capacity rationally, allocate resources reasonably, and enhance international competitiveness. The provincial government held a videoconference and sent four emergency notices

it is reported that since 2006, Baoding city has put forward the strategic idea of relying on Baoding high tech Zone to build a "Baoding · China Power Valley", fully cultivating six industrial systems of optoelectronics, wind power, power saving, power storage, power transmission and transformation, and power automation, and has established the leading position of Baoding high tech Zone in the domestic new energy industry

the industry is becoming more and more mature

Li Junfeng said that since new energy is a strategic and leading industry of the national economy, it plays a very important role in stimulating economic growth, adjusting the industrial structure and transforming the development mode. A new energy revolution is brewing all over the world. The United States, Japan, Europe and other countries and regions are vigorously supporting new energy in the international financial crisis and putting forward slogans such as "Green New Deal" and "green recovery", all of which are seizing the strategic leadership

from the perspective of world development trends, most new energy technologies are becoming more and more mature, especially the photovoltaic industry is developing rapidly, and the industrial scale, economy and marketization degree are improving year by year. Among them, crystalline silicon photovoltaic cells will develop in the direction of high efficiency, low cost and thin sheet. With the breakthrough of thin-film battery technology and the gradual realization of industrialization, the cost of photovoltaic power generation will fall to the level that can compete with conventional fossil energy power in a very short time, so as to accelerate the transformation from supplementary and alternative energy to major and mainstream energy, and the market competition will be very intense

insiders said that the basic feature of a mature industry is a fierce market, so flexible packaging manufacturers basically do not need competition. They believe that through fierce market competition, strict environmental protection policies and energy conservation and emission reduction measures, the photovoltaic industry, as a clean and brand-new industry, will usher in a broader development space
