As China's largest primary energy supplier, we are committed to the scale of clean new energy while fully pursuing the clean energy of traditional energy. Ling Wen, general manager of the National Energy Group and academician of the Chinese Academy of Engineering, recently revealed at the Xi'an Photovoltaic Industry Development Summit Forum that the National Energy Group has made a major breakthrough in the copper indium gallium selenide (CIGS) thin film photovoltaic technology, and the next step will be to enter the photovoltaic industry. Power generation industry. Industry experts believe that the energy giant hair copper indium gallium selenide thin film photovoltaic industry will certainly promote the deep integration of photovoltaic technology and construction engineering, the industry calls for years of photovoltaic building integration process is expected to accelerate. Copper indium gallium selenide thin film photovoltaic: strange name is a good technology On August 10-12, 2018, at the 3rd China Xi'an Photovoltaic Industry Development Summit Forum and Exhibition, the copper indium gallium selenide thin film photovoltaic power generation technology exhibited by the National Energy Group was quite eye-catching. "Copper, Indium, Gallium, Selenium? The name is weird!" Participants including many media reporters stopped to watch and had a lot of questions. “This refers to a technical way of converting light energy into electrical energy using copper indium gallium selenide thin film solar cells.†Ling Wen, general manager of the National Energy Group and academician of the Chinese Academy of Engineering, acted as an instructor. He said that the copper indium gallium selenide thin film solar cell refers to a crystalline thin film solar cell whose absorption layer is composed of copper (Cu), indium (In), gallium (Ga), and selenium (Se) in an optimum ratio. Ling Wen said that copper indium gallium selenide thin film photovoltaic cells have many advantages. First, lightweight, that is, light weight, easy to install; second, weak light power generation performance, such as Xi'an in this season, when the sun comes out at 6 o'clock in the morning, it starts to generate electricity; third, the power attenuation is low. Another feature is the concept of rich colors and aesthetics in architecture. The copper indium gallium selenide thin film photovoltaic cell is thus internationally called "the next generation of very promising new thin film solar cells". "The biggest advantage of copper indium gallium selenide thin film photovoltaic cells is the high photoelectric conversion efficiency." Ling Wen stressed that in recent years, the research and industrialization of copper indium gallium selenide thin film solar cells have progressed rapidly, and the world record of conversion efficiency has been continuously refreshed. The highest conversion efficiency record in the laboratory has reached 22.9%. According to reports, copper indium gallium selenide thin film solar cells can be widely used in remote mountainous power stations, agricultural light complementary, fishing and light complementary precision poverty alleviation projects, photovoltaic building integration (BIPV), large-scale ground photovoltaic power plants, distributed photovoltaic power plants, cities Landscape, tourism, transportation and other fields. Copper indium gallium selenide thin film solar cells can also be customized to produce different color and pattern components, suitable for different market applications and requirements, especially to meet architectural aesthetics requirements such as color, specifications, etc. Low requirements, can be installed on the facade of the building. National Energy Group: To be a leader in thin-film photovoltaic power generation As we all know, the National Energy Group, which was reorganized by China Guodian Group and Shenhua Group in November 2017, has four “the world's most†– the largest coal production company, the largest thermal power generation company, the largest wind power generation company and the largest coal-to-liquid oil. Coal chemical company. When will this energy giant focus on the photovoltaic industry? Ling Wen told reporters that as early as 8 years ago, a team of scientists from the Shenhua Low Carbon Research Institute began to track the technology of copper indium gallium selenide thin film photovoltaic cells. Scientists have found that copper indium gallium selenide thin film photovoltaic power generation represents the most promising direction of solar energy development. At the beginning of the establishment of the National Energy Group, the copper indium gallium selenide thin film solar power industry was regarded as a strategic emerging development industry, and the copper indium gallium selenide thin film photovoltaic building integration project was launched. “At present, we have built a “five-in-one†development and innovation system for the integration of copper indium gallium selenide thin film photovoltaic power generation technology, equipment manufacturing, component production, ground power station and photovoltaic building.†Ling Wen said that the technology is first established, including Technical innovation team including many German technicians; furthermore, we have cooperated with Shanghai Electric Group to realize the localization of equipment production; thirdly, the production of photovoltaic modules, we have built a copper indium gallium selenide solar cell module company in Chongqing, at the end of this year. The first batch of components will be introduced, which will reduce costs and improve efficiency on a large scale. Fourthly, we will be the world's largest power generation company. The photovoltaic power generation will complement the thermal power, wind power and hydropower to maximize the application efficiency. The fifth and most important point is that we will cooperate fully with domestic construction companies to promote the integration of photovoltaic buildings. According to Ling Wen, in order to accelerate the integration process of copper indium gallium selenide thin film photovoltaic building, the National Energy Group also undertook the general project of “Application Research of CIGS Solar Thin Film Power Generation Technology in Photovoltaic Building Integration†by the Ministry of Housing and Urban-Rural Development, and integration. Component research, integrated system and assembly technology optimization research, energy integration system research, component production and processing technology optimization research, product comprehensive performance test research, copper indium gallium selenide building energy control and experimental platform research, engineering cost research, technical economic evaluation research 10 sub-projects such as demonstration building research, standards and norm formulation research; at the same time, also undertaken a number of demonstration projects. "In the second half of this year to the first half of next year, six entity demonstration projects in Beijing, Jiangsu, Guangdong, Hainan, Sichuan and other provinces and cities will be completed one after another, forming a complete system of sub-project families and demonstration projects." Ling Wen said. "We have reason to believe that National Energy Group will become one of the world's leaders in copper indium gallium selenide thin film photovoltaic technology." A revolution in the construction sector: from energy consumers to producers For the National Energy Group to enter the copper indium gallium selenide photovoltaic power generation industry, industry experts commented that this move will accelerate the integration process of photovoltaic buildings, transform buildings from energy consumers into energy producers, and become a revolution in the field of urban construction. "Photovoltaic Building Integration (BIPV) refers to a technology that integrates solar power generation products and is part of the building." Dr. Tang Yang, National Energy Group's Center for Green Energy and Building Research, said that this is related to the solar photovoltaic system attached to the building. (BAPV) is completely different. As a part of the external structure of the building, the battery not only has the function of generating electricity but also the function of building materials. It can also enhance the aesthetics of the building and form a perfect unit with the building. According to data from the Ministry of Housing and Urban-Rural Development, China's building energy consumption accounts for about 30% of the total energy consumption of the whole society. Photovoltaic building integration has green energy conservation, reduces carbon emissions, enhances architectural aesthetics, replaces some building materials, reduces building costs, and improves electricity efficiency. Great advantages such as saving land resources, reducing atmospheric and solid waste pollution, and protecting the ecological environment. "However, most of the current photovoltaic building integration projects are to install solar photovoltaic modules in the form of photovoltaic curtain walls on the facade of buildings. It should be called the 'primary edition' of photovoltaic building integration." Tang Yang told reporters that copper indium Gallium Selenide Thin Film Photovoltaic Building Integration (CIGS-BIPV) is a fusion of copper indium gallium selenide photovoltaic technology and construction engineering. The building integrates copper indium gallium selenide thin film photovoltaic modules as a whole to design and construct photovoltaic modules. An inseparable part of the building, such as a wall, not only has the building function of sheltering from wind, rain, heat insulation, sound insulation, but also the most developed form of distributed energy. Optimize control of heating, ventilation, air conditioning, comprehensive integration of natural lighting, photovoltaic power generation, photothermal utilization, DC power supply, intelligent microgrid, and automation systems, complete integration and optimization of building design and operation, and realization of buildings The various comfort indicators, to achieve the true sense of photovoltaic building integration, is the "advanced version" of photovoltaic building integration. Ling Wen believes that the integration of copper indium gallium selenide thin film photovoltaic building in the construction industry will generate huge social and economic benefits, and will also bring about a profound transformation of energy and architecture. In the energy sector, the spread of distributed green clean energy will be promoted, and buildings will be transformed from energy consumers to energy producers, and cities will be transformed from energy-consuming cities to energy-production cities. In the field of architecture, the direction of building development is gradually changed, and the concept of green, clean and integrated is deeply rooted in the hearts of the people, reconstructing urban texture and urban temperament, and increasing urban richness and diversity.
