In a recent development, LONGi, a prominent player in the solar energy sector, has made a significant breakthrough in the realm of solar cell technology. The company has achieved a remarkable 35.5% efficiency for its silicon-perovskite tandem solar cell, as reported at the 2026 Solar and Energy Storage Innovation Conference. This achievement marks a new record for the technology, showcasing LONGi's continued innovation and leadership in the industry.
The journey towards this milestone began with a series of efficiency improvements over the past three years. LONGi's tandem cell efficiency has been steadily rising, starting at 33.9% in November 2023 and reaching 34.6% in June 2024. The latest 35.5% efficiency is a testament to the company's relentless pursuit of excellence and its commitment to pushing the boundaries of what's possible in solar technology.
This breakthrough is not limited to smaller-scale cells. LONGi has also demonstrated its prowess in larger devices, reporting efficiencies of 34.3% for a 261cm² tandem cell and 32.2% for a 274cm² tandem cell. These results showcase the company's ability to maintain high efficiency standards across various cell sizes, making it a versatile and reliable choice for a wide range of solar applications.
Furthermore, LONGi's work extends beyond individual cells. The company has achieved conversion efficiencies of 31.4% and 29.4% for tandem modules, with both results independently certified and included in the latest edition of the Solar Cell Efficiency Tables. This certification further solidifies LONGi's position as a trusted and innovative leader in the solar energy industry.
One of the most exciting aspects of LONGi's recent achievements is the inclusion of its 35.2%-efficient two-terminal crystalline silicon-perovskite tandem cell in the 68th edition of the Solar Cell Efficiency Tables. This recognition highlights the significant impact of LONGi's technology on the industry and its potential to shape the future of solar energy.
Additionally, LONGi's hybrid interdigitated back contact (HIBC) cell has achieved a conversion efficiency of 28.13%, surpassing its previous record of 28.04% set in January. This improvement was certified by the Institute for Solar Energy Research Hamelin (ISFH) in Germany, further emphasizing the company's commitment to quality and innovation.
The implications of these advancements are far-reaching. LONGi's modules, fabricated using the high-efficiency cells, have achieved a conversion efficiency of 26.4%, up from the previous record of 26%. This result was certified by the US National Laboratory of the Rockies (NLR), further validating the company's technological prowess.
Moreover, LONGi's recent launch of the Hi-MO 9 Prime module series at Intersolar Europe 2026 is a testament to its ongoing innovation. The series features a power output of 680W and a module conversion efficiency of 25.2%, showcasing the company's ability to balance high efficiency with practical applications.
In conclusion, LONGi's recent achievements in solar cell technology are a testament to the company's unwavering commitment to innovation and its ability to push the boundaries of what's possible. With a focus on efficiency, versatility, and practical applications, LONGi is poised to shape the future of solar energy and inspire further advancements in the industry.
