LONGi Breaks New Ground with Record Efficiency for Solar Cells and Modules

LONGi's Groundbreaking Achievements in Solar Technology

In a substantial advancement for renewable energy, LONGi has recently announced two critical breakthroughs in solar technology that are set to revolutionize the photovoltaic landscape. The company’s Hybrid Interdigitated-Back-Contact (HIBC) solar cell has earned international recognition, achieving a photoelectric conversion efficiency of 28.13%. This remarkable feat was validated by the Institute for Solar Energy Research Hamelin (ISFH) in Germany, positioning LONGi closer to the theoretical efficiency limit of crystalline silicon solar cells. This follows closely on the heels of another record set by LONGi in January 2026, which reached an efficiency of 28.04%.

In addition to the advancements in solar cell efficiency, LONGi also announced that modules constructed using its HIBC cells have been certified by the U.S. National Laboratory of the Rockies (NLR), achieving a groundbreaking efficiency of 26.4%. This follows the previous benchmark of 26%, further solidifying LONGi's status as a leader in solar technology.

The HIBC cells developed by LONGi's Central RD Institute represent the pinnacle of innovation in solar technology, integrating the best features of various cell technologies. Innovative techniques such as in-situ Patterned Edge Passivation (iPET) and Laser-Induced Crystallization modification (LIC) have been employed to enhance structural designs, select superior materials, and refine fabrication processes. These enhancements have culminated in significant improvements in optical performance, interface quality, and charge transport efficiency, paving the way for the widespread commercialization of ultra-high-efficiency crystalline silicon cells.

In April 2026, the respected global photovoltaic media outlet TaiyangNews unveiled its ranking of commercialized mass-produced module efficiencies. Remarkably, LONGi's EcoLife series modules, powered by the newly developed HIBC technology, took the lead with a mass-production efficiency of 25%. This achievement signifies the successful transition from laboratory research and development to full-scale commercial application of HIBC cells, yielding a cutting-edge clean energy solution. The company’s offering is lauded for its effectiveness, energy yield, aesthetic versatility, along with safety and reliability certifications.

LONGi’s longstanding commitment to clean energy is underscored by its comprehensive solutions encompassing: "Green Power + Green Hydrogen + Energy Storage." With an unwavering focus on technology iterations fueled by independent research, the company consistently delivers high-quality products suitable for diverse application scenarios worldwide. Looking вперед, LONGi is dedicated to continuing its trajectory of technological innovation, speeding up the conversion of laboratory efficiencies into large-scale manufacturing outputs. The company aims to support the global transition towards greener energy by providing competitively sustainable clean energy solutions and contributing to a zero-carbon, environmentally friendly ecosystem.

In conclusion, LONGi's innovative strides in solar technology not only highlight its leadership in the renewable energy sector but also set a solid foundation for a more sustainable future as societies move towards cleaner energy sources. As the company pursues new milestones, its impact on the global energy landscape will surely continue to expand, empowering customers and communities towards achieving their energy goals.
