26.81%! Longi Green Energy Heterojunction Cell breaks the world record for the efficiency of silicon solar cells

Longi Green Energy Heterojunction Cell Breaks the World Record for Silicon Solar Cell Efficiency

On November 19, LONGi Green Energy announced to industry officials during the 16th China New Energy International Expo and Summit Forum at 2022NEX that the company has received the latest certification report from the Institute for Solar Energy Research Hamelin (ISFH) in Germany. The report shows that 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-based 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.

Li Zhenguo, founder and president of LONGi Green Energy, said: "Improving the conversion efficiency and reducing the cost of electricity is the eternal theme of the development of the photovoltaic industry. The efficiency of solar cells is the beacon of photovoltaic technology innovation, and every breakthrough of 0.01 is full of challenges. Especially for crystalline silicon Batteries account for nearly 95% of the current photovoltaic market, so the determination of the ultimate efficiency of crystalline silicon solar cells also demonstrates the development potential of photovoltaic technology and the development direction of the photovoltaic industry, which is of great significance in the entire photovoltaic field."

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.

It is understood that the research and development team of Longji Green Energy’s high-efficiency crystalline silicon heterojunction cell that broke the world record this time has continuously broken and refreshed the original world record for silicon heterojunction cells from June 2021 to the present, increasing from 25.26% to 26.81%, The miracle that the absolute value increased by 1.55% in one year and four months was realized. Especially within more than a month, LONGi Green Energy achieved a new record for the efficiency of silicon solar cells with 26.74%, 26.78%, and 26.81% respectively. determination. And this kind of mature technology and the world record of large-area all-silicon wafer are also very rare in the entire history of photovoltaic technology development.
