In the field of renewable energy, LONGi Green Energy Technology Co., Ltd. ("LONGi") has once again made an important technological breakthrough. In a research paper published in the journal Nature, the company announced that the photoelectric conversion efficiency of crystalline silicon cells exceeded 27% for the first time after the innovation of the all-laser patterning process. This achievement has not only attracted wide attention in the academic community, but also has a far-reaching impact in the industry, marking another leap forward in photovoltaic technology.
Key technological breakthroughs
LONGi's efficiency breakthrough is the result of the in-depth research of the Academia Sinica team in two key areas: silicon wafer manufacturing and surface passivation contact technology. The team has developed a new type of dense HJT passivation contact technology, which increases the process temperature to 240°C, successfully breaking through the industry's long-standing bottleneck in HJT preparation in the range of 180-210°C. This increase in temperature not only promotes the improvement of the photoelectric conversion efficiency of the battery, but also lays the foundation for the future production of low-cost and high-efficiency back-passivated (BC) cells.
This breakthrough will propel the industry to a major step in the direction of ultra-efficient battery technology. LONGi's innovative infrastructure combines heterojunction technology and BC structure to provide a new solution for improving cell efficiency. This achievement not only represents technological progress, but also injects new impetus into the future development of the photovoltaic industry.

Long-term innovation and technology accumulation
LONGi's success is not accidental, but the result of its long-term insistence on technological innovation and continuous R&D investment. Over the past two decades, crystalline silicon cell manufacturing has undergone three major iterations of technology. From the initial Al-BSF era, when the cell efficiency was less than 20%, to the PERC era, where the efficiency was still less than 25%, and then to the successful breakthrough of 25% after the upgrade of TOPCon technology, LONGi has always been at the forefront of photovoltaic technology and has continuously promoted the development of the industry.
LONGi's technological breakthrough demonstrates the company's deep accumulation in the field of cutting-edge technology and strong R&D capabilities. With the continuous development of photovoltaic technology, LONGi's leading position will be further consolidated and provide strong technical support for the development of the global photovoltaic industry.
The promotion of industrial ecology
LONGi's achievements are not only technological innovation, but also promote the comprehensive development of the photovoltaic industry ecosystem. The company plans to cooperate with the upstream and downstream of the industry to promote the practical application and implementation of the new generation of BC technology to help the photovoltaic industry move towards a more efficient and sustainable future. Through close collaboration with major partners around the world, LONGi will continue to expand its market share and promote the standardization and popularization of global photovoltaic technology.
In this process, LONGi will also increase its efforts to develop the international market. With the rising global demand for renewable energy, LONGi's internationalization strategy will further strengthen the company's global competitiveness. The company hopes to promote China's photovoltaic technology and products to more countries through international layout, and promote the transformation of the global energy structure.
Future outlook
This scientific research achievement of LONGi not only demonstrates its self-confidence in its own technical strength, but also provides strong support for the internationalization of Chinese photovoltaic brands. As LONGi continues to expand in the global market, it is expected that it will contribute more wisdom and strength to the transformation of the global energy structure. In the future, LONGi plans to continue to increase investment in R&D, devote itself to further breakthroughs in ultra-efficient battery technology, and promote its application globally.
It is expected that with the maturity of new technologies, the production cost of photovoltaic cells will continue to decrease, thereby further enhancing their market competitiveness. LONGi's research results will lead the entire industry to develop in the direction of higher efficiency and lower cost, laying a solid foundation for the sustainable growth of the photovoltaic industry.
This breakthrough of LONGi is not only a technological leap, but also a strong impetus for the future development of the photovoltaic industry. It indicates that photovoltaic technology will play a more important role in the future energy field and become an important driving force for the global energy transition.
To sum up, LONGi's achievement of exceeding 27% in crystalline silicon cell efficiency for the first time will point out the direction for the development of the photovoltaic industry and promote the continuous progress of industry technology. With LONGi's continuous efforts, we have reason to believe that the photovoltaic industry will usher in more brilliant achievements in the future and contribute to global sustainable development.
