First time in history! China sets new world record for efficiency of silicon solar cells

BAUFAR : LONGi Green Energy recently, according to the latest certification report of the Institute for Solar Energy Research Hamelin (ISFH) in Germany, the conversion efficiency of the silicon heterojunction cell independently developed by LONGi Green Energy reached 26.81%.

Martin Green, the "father of solar energy in the world" and a professor at the University of New South Wales, announced via video on November 19 that Longi Green Energy's cell efficiency of 26.81% is currently the highest record for the efficiency of silicon solar cells in the world, regardless of the technical route. This is the latest world record after five years since a Japanese company created a monocrystalline silicon cell efficiency record of 26.7% in 2017. It is also the first time in photovoltaic history that a Chinese solar technology company has set a world record for silicon cell efficiency. Zhang Yuzhuo, secretary of the party group of the China Association for Science and Technology, said that breaking the world record is a milestone in the development history of my country's photovoltaic industry. The confidence and determination to go to the forefront of the world in the field. This was unimaginable 10 years ago. From the embarrassing situation of "three heads outside" and being constrained by others, to firmly occupying the top spot in the world's photovoltaic industry and becoming a Chinese business card in the new era, China's photovoltaics took less than 10 years. Among them, China's photovoltaic industry has experienced several ups and downs, and a rule can be summed up, that is, technological innovation is the core driving force for the continuous advancement of China's photovoltaic industry. McKinsey’s comparison radar chart of core technologies between China and the United States shows that China’s photovoltaic industry technology is definitely ahead of the United States, leading the development direction of the global photovoltaic industry. From the production links of silicon wafers, batteries and modules, Chinese photovoltaic companies have been leading the technological trend of the global photovoltaic industry.

This time, Chinese photovoltaic companies have set the highest record for the efficiency of silicon solar cells in the world, which has undoubtedly once again consolidated the technical strength of China's photovoltaic industry, pushed the limit of human commercial application of solar energy to new heights, and enhanced the core competitiveness of China's photovoltaic industry . In addition, the core of the development of photovoltaic technology has always revolved around improving efficiency and reducing the cost of electricity. The world record for the conversion efficiency of silicon solar cells created this time also provides more room for reducing the cost of electricity. "With the same area, absorbing the same light, the more electricity that can be emitted, the better." Li Zhenguo, founder and president of LONGi Green Energy, said that taking solar cells as an example, based on 20% conversion efficiency, after calculation , every percentage point increase in conversion efficiency can save more than 5% of the cost for downstream power stations. Therefore, even a 0.01 percentage point increase in battery conversion efficiency is of great significance. Among them, Chinese photovoltaic companies, including LONGi Green Energy, have made great efforts to continuously increase investment in scientific research and technological innovation. Looking forward to the future, from the perspective of carbon peak carbon neutrality, by 2030, the world's newly installed photovoltaic capacity needs to reach 1500GW-2000GW, and the continuous installation for 30 years can form an effective support for the global energy transition. Therefore, photovoltaic companies or industries should try their best not to be influenced by the outside world, return to the main track of battery efficiency improvement, increase investment in research and development of new battery materials and new technologies, do a good job in scientific and technological innovation, and devote themselves to reducing costs and increasing efficiency, and improving energy efficiency. The competitiveness of the photovoltaic industry promotes the large-scale application of clean energy. This is the top priority of the current and future development of China's photovoltaic industry.
