The EU's "double reaction" is aggressive and the "surplus" of production capacity is shrouded in the shadows. Faced with the photovoltaic crisis of internal and diplomatic difficulties, companies have responded with measures, either adjusting their production capacity and streamlining their structure, or switching to emerging markets to seek new breakthroughs. At the same time, improving conversion efficiency, reducing power generation costs, increasing cost-effectiveness, and enhancing product competitiveness have become competitive killers. Some companies, including Yingli Group and other companies that have mastered industry core technologies and strong innovation capabilities, have shown a strong situation in this crisis. Take control and market control. At the second session of the First National Academic Committee of the State Key Laboratory of Photovoltaic Materials and Technology held on October 10, the reporter was informed that the fifth-generation "Panda" N-type single crystal independently developed by Yingli Group, a well-known photovoltaic company in China The average conversion efficiency of silicon-efficient batteries has reached 19.5%, an increase of 0.5 percentage points from the previous year, and it can generate nearly 100 million yuan for companies each year. It is understood that "panda" battery is one of the world's three most efficient solar cells for commercial production. Dr. Song Dengyuan said that compared with the current conventional P-type silicon solar cells, the "Panda" N-type single crystal silicon high-efficiency battery has a simple structure, the production cost is 30% lower than similar products, and the photoelectric conversion efficiency is high. In particular, it is worth mentioning that the "Panda" N-type single crystal silicon high-efficiency battery adopts phosphorus diffusion to form an effective back-field, and the contact mode is achieved through a similar frontal grid line design, so that the battery has double-sided power generation capability, thereby enhancing power generation. effectiveness. It is reported that for every one percentage point increase in conversion efficiency of solar cells, the cost of generating solar modules can be reduced by 7%. The increase of 0.5% in "Panda" battery, in addition to reducing the cost of photovoltaic power generation, can generate nearly 100 million yuan for the company. According to reports, "Panda" N-type single crystal silicon high-efficiency battery project is Yingli Group and Europe's leading solar cell research institute Dutch National Energy Research Center (ECN) and the world's leading photovoltaic equipment and automation system supplier Amtech (Amtech) The joint R&D project conducted by the company is based on the research and development of the State Key Laboratory of Photovoltaic Materials and Technologies. In 2011, it won the second prize of the National Energy Technology Progress Award. automatic black aluminum frosted glass,sectional residential garage door,Automatic Sectional Customized Aluminum Frameless 16x8 Foshan City JBD Home Building Material Co.,Ltd. , https://www.jbdhome.com
