local time, Longji Green Energy officially released a major technological achievement in Europe: the high and low temperature composite passivation back contact battery (HIBC) independently developed by the company has been tested and certified by the German Hamelin Solar Energy Research Institute (ISFH), with a photoelectric conversion efficiency of 28.29%.

This is the third time that Longji has refreshed the world record of crystalline silicon cell efficiency this year . This year, Longji has refreshed the battery efficiency to 28.04%, 28.13% and 28.29%. The efficiency of the newly created crystalline silicon battery has approached the technical ceiling, reaching 96.2% of the theoretical limit.
HIBC battery is the landmark achievement of Longji Green Energy's R & D strategy of "wide research and narrow investment". This technology integrates the advantages of many mainstream battery technologies, from battery structure design, core material preparation, production process to efficiency theory model, and completes a comprehensive and systematic innovation and upgrading. It is also a strong proof of Longji's continuous deep cultivation of high-efficiency battery track, adherence to independent innovation and core technology.
Relying on HIBC battery technology, the simultaneous appearance of more than 700 W components marks the successful mass production of this cutting-edge technology, and also proves that Longji has the ability to build high-end photovoltaic products and realize the commercial application of cutting-edge technology.
Based on the wave of global energy change, Longji Green Energy has always focused on the layout of the whole clean energy industry chain, and made every effort to build an integrated solution of "green electricity + green hydrogen + energy storage". In the future, Longji will continue to adhere to independent innovation, lead the development of the industry with technology iteration, export full-scene and high-quality photovoltaic products to the global market, help the global energy transformation in depth, and work together to build a new pattern of green energy with zero carbon and sustainable development.
