On August 5th, the key project of the National 863 Program, "Efficiency of more than 20% of Key Technologies and Demonstration Production Lines for Industrialization of Novel Electrode Structure Crystalline Silicon Cells," was held in Baoding. Experts and representatives from the Ministry of Science and Technology, the Hebei Provincial Department of Science and Technology, the Baoding Science and Technology Bureau, the Baoding Hi-tech Zone and the Yingli Group and other subject undertaking units attended the kick-off meeting. Relying on the national 863 project undertaken by Yingli Group's State Key Laboratory of Photovoltaic Materials and Technology, the laboratory conversion efficiency of Yingli's new-generation high-efficiency MWT "panda" solar cell will exceed 21%.
According to reports, the 863 project was led by Yingli Group's state key laboratory and used research, production, and research to conduct research and development. The participating units included five scientific research institutes, universities and enterprises. This 863 project is divided into three tasks, among which the Yingli Group and the Institute of Semiconductors of the Chinese Academy of Sciences, the Institute of Microelectronics of the Chinese Academy of Sciences and the Beijing University of Aeronautics and Astronautics jointly undertake the tasks of “efficiency of more than 20% for N-type single-crystal silicon high-efficiency Matter cell and demonstration production lineâ€. The key core technology of N-type MWT solar cells.
Dr. Song Dengyuan, chief technology officer of Yingli Group, stated that the project of "efficiency of more than 20% N-type single crystal silicon high-efficiency MWT battery and demonstration production line" is one of the important projects to achieve the "12th Five-Year Plan" for the development of solar power technology. Approved by the Ministry of Science and Technology in February 2012, the goal is to re-innovate on the basis of Yingli Group's existing “panda†single crystal battery technology, achieve integration of MWT technology with N-type crystalline silicon cells, and increase N-type crystalline silicon cells Electrical performance indicators improve battery conversion efficiency and reduce battery costs.
It is understood that the research on N-type silicon single crystal high-efficiency solar cells is a research hotspot in the field of national photovoltaics. How to achieve breakthroughs in China's PV industry through this technology and development has an important significance for the improvement of the overall level of China's photovoltaic industry. The "National Twelfth Five-Year Plan for Scientific and Technological Development" clearly stated that during the "12th Five-Year Plan" period, the country will focus on the development of design, integration, high-efficiency and low-cost solar cells, components and complete sets of equipment for large-scale photovoltaic systems.
Dr. Song Dengyuan stated that the project of "efficiency of more than 20% N-type single crystal silicon high-efficiency MWT battery and demonstration production line" aims at the international advanced level and will adopt advanced technology with independent intellectual property rights and a new technical route to achieve efficient N-type single crystal silicon. The solar cell conversion efficiency has been further improved and an annual production capacity of 30MW demonstration production line has been completed. The smooth implementation of the project will enable China's photovoltaic technology to continue to be at the leading international level.
It is understood that as an internationally renowned photovoltaic company, Yingli attaches great importance to scientific and technological innovation, builds a scientific research platform, increases research investment, and continues to strengthen the construction of research teams. State Key Laboratory of Photovoltaic Materials and Technology of the Ministry of Science and Technology, National Energy Photovoltaic Technology Key Laboratory of the Energy Administration, Postdoctoral Workstations and other research platforms have settled in Yingli, which represents the highest level of domestic R&D of photovoltaics.
Relying on Yingli’s large technical team and a state-of-the-art R&D cutting-edge technology platform, Yingli has undertaken 3 projects in the national 863 program, 2 projects in the 973 program, and 1 project in the national science and technology support project in recent years. The research and development content relates to the efficiency of N-type silicon single crystals. Batteries, new silane-based high-purity silicon preparations, and other core frontier technologies in the photovoltaic industry chain. In 2011, Yingli Technology Innovation Project reached 265 items. At present, Yingli "Panda" N-type monocrystalline silicon cell laboratory conversion efficiency of 20%, is one of the world's three major high-efficiency solar cells.
This diameter of this series glass bead is two or three times bigger than regular beads. The surface part beyond paints is higher than regular beads; hence the reflectivity of road marking has been increased, especially in rainy, foggy areas.
The diameter is 850-1400mm (20-14mesh) with ≥80% of roundness. The special coating on the surface of glass bead can improve the adhesion between paint and glass beads, thus the longevity can be increased.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
