Recently, the 48th Institute of China Electronics Technology Group Corporation successfully developed a series of high-efficiency color solar cells, becoming the first photovoltaic power generation company that successfully developed this product. Content from the photovoltaic portal news website Global Photovoltaic Network In the research and development process of this series of high-efficiency color solar cell products, researchers broke through the conflict between color and high conversion efficiency. After arduous trials, they explored a complete set of equipment and processes to ensure The solar cells of various colors such as brown, gold brown, red, gray blue, yellow, and blue-green were prepared under the premise of high photoelectric conversion efficiency of the battery, and mass production was successfully achieved. The average conversion efficiency of mass production of high-efficiency color solar cells reached 17.5%.
At present, ordinary solar cells are blue. With the rapid development of photovoltaic power generation technology, not only the conversion efficiency of solar cells has been continuously improved, but also the appearance of the products has become more demanding. The 48 series of high-efficiency color solar cell products that were developed are aimed at the new needs of the photovoltaic power generation application market. They have the dual characteristics of “high efficiency†and “color†and can be widely used in photovoltaic power generation plants and photovoltaic power generation buildings. The construction of the project will be a perfect combination of energy conservation and beautification. It is particularly in line with the requirements for the construction of a “two-type†society. This will surely become another new hot spot for the solar cell application market.
According to the responsible person's introduction, ordinary solar cells are wearing a blue "uniform", photovoltaic power generation application technology has been widely used, not only put forward higher requirements for solar cell conversion efficiency, but also look forward to more breakthroughs from "old fashioned" to "fashion" . It is reported that the technical experts of the China Electronics 48 Institute developed and successfully produced highly efficient color solar cells. They have taken the lead from a single “blue†tone and derived various colors such as brown, gold brown, red, gray-blue, yellow, blue-green and so on. Photovoltaic power plants and photovoltaic power generation buildings can be both energy-saving and aesthetically pleasing, so that both "fish" and "bear bear" can achieve both, and mass production can be successfully achieved. Content from the photovoltaic portal news website Global Photovoltaic Network Solar cells change color from a single color, is an important breakthrough in the development of solar cells. CLP-48 has developed a crystalline silicon series of high-efficiency color solar cells. The average conversion efficiency of mass production is above 17.5%, which has reached the current solar cell conversion efficiency for large-scale production.
Taking the Zhongdian 48 as the leading photovoltaic power generation industry is an emerging industry in our province. With its core equipment as the basis, Hunan's crystalline silicon solar photovoltaic power generation industrial chain has shown signs of divination, and its immediate goal is to sprint billions of industrial clusters. It is understood that the wide application of photovoltaic power generation technology can not only lead people to return to low-carbon society, but also save on living expenses.
The color solar cells conquered our country's pavilion designer to enter our country pavilion to visit all the audiences. From the entrance to the exit, we will see the wonderful effect of the colorful solar cell components. Red echoes each other and complement each other.
There is a little story in there. “In the beginning, our country's museum designers used alloy aluminum plates and did not consider solar panels at all.†Zhao Feng, chief engineer of Shenzhou Optoelectronics, revealed that “because the appearance requirements of the entire building are very high, the concept of green building is just Some conventional solar panels were installed on the roof of China's pavilion, and when the China Pavilion project department learned about the information of high-efficiency color solar cells, it persuaded the designers to use color solar panels to replace the aluminum alloy plates. After strict inspection and inspection, it was 1 km from the China Pavilion. Looks down on the viewing platform to dismantle the aluminum alloy sheet that was previously laid, and all the high-efficiency color solar panels produced by Shenzhou Optoelectronics have been laid."
On February 10, the high-efficiency color solar power system was formally operated in the China Pavilion. This is the first application of high-efficiency color solar cells in buildings. The entire solar power system installed 2,800 pieces of high-efficiency color double-glass solar modules, with an installed capacity of 250 kilowatts and an average annual electricity consumption of about 280,000 kilowatt-hours, which has obvious environmental protection benefits for energy saving and emission reduction.
Targeting the market to engage in research and development, breaking through the application of photovoltaic power generation and building integration and grid-connected power generation, is considered to be the largest market for photovoltaic power generation in the future and the main direction. However, the application of conventional solar cells to buildings is subject to a fundamental constraint because buildings, as environments and urban landscapes, require very high color appearance. Zhao Feng told reporters that conventional solar cells have only a single color, and if the conventional solar cells are made into other colors, the conversion efficiency of the battery will be drastically reduced. Therefore, conventional solar cells will face a dilemma when they are applied to buildings: either sacrifice construction. The appearance of the object is beautiful, or the power generation efficiency of the photovoltaic power generation system is sacrificed.
An accidental chance to study this difficult problem for many years Zhao Feng met with the honor of “the father of Chinese photovoltaic power generation†and was Professor Huang Huiliang of Tsinghua University in Taiwan. At the end of 2008, Zhao Feng and Huang Huiliang's team had joint research. Under the joint efforts of Shenzhou Optoelectronics Co., Ltd., it solved the dilemma of high efficiency and color of solar battery products in one fell swoop, developed a high-efficiency color solar cell, and applied for a patent for invention.
In Zhao Feng's view, technological innovation is the core of the solar industry becoming bigger and stronger, and if the solar energy industry keeps its vitality, it must also aim at the market to engage in innovation. "In 2009, Shenzhou Optoelectronics increased investment in technology research and development based on market demand, and applied for 7 patents, of which 5 had already received notifications of patent acceptance, 2 patented products were put into production that year, and they had a profit that year. This year, we also 10-15 patents will be applied."
Why is the domestic market difficult to open?
After the products were on the World Expo, Shenzhou Optoelectronics was immediately highly concerned by domestic and foreign counterparts. Orders from companies were also incessant, but most of them were from France, the United States, and Brazil. There were few domestic orders. This makes the application of solar energy products have unlimited success Zhao Feng often feel sad.
“In this drought in southwest China, we designed a series of solar-powered extraction rods for deep-well wells in dry areas. The dry areas are bright and sunny all day, and those areas are relatively poor, and when electricity is often unavailable, even if it is Wells and wells have water in them, but they can't pump without electricity. So we designed these products to solve some of the difficulties for the people in the disaster area. If there is a sun, the pump will automatically pump water.
For another example, the tunnels in the mountains can be fully illuminated by solar power. Through our design, we can not only beautify the environment but also save energy and environmental protection..."
"With the color, solar cells can be used in a variety of buildings, architects are more willing to use it." To strengthen people's understanding of the prospects of solar energy applications, Zhao Feng also proposed photovoltaic power generation target = "_blank "> Photovoltaic power generation environment integration has a new concept. Under the guidance of this idea, solar energy products can be used not only in buildings, but also in major projects such as gardens, green belts, scenic areas, bridges, farmland irrigation, and even the South-to-North Water Transfer Project, which greatly expands solar photovoltaic power generation systems. Application market.
He said that the reasons for such a situation are, on the one hand, the relevant policies of the country are not yet clear, especially the lack of subsidies for solar power generation and on-grid tariffs, resulting in high cost of commercialization; on the other hand, some local government departments are facing solar power projects. There are also misunderstandings. There is also a certain degree of distrust in solar power generation and prejudice. As a result, solar energy products cannot be widely promoted, which in turn causes excessive costs.
"If these policy bottlenecks can be resolved at an early date, China's solar energy industry will become bigger and stronger, and will do more long-term." Zhao Feng finally said.
