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, a feat that represents a new record for this innovative technology. This achievement comes on the heels of a series of efficiency improvements reported by LONGi over the past three years, showcasing their commitment to pushing the boundaries of solar energy conversion.
What makes this achievement even more impressive is the company's ability to consistently raise the bar. In November 2023, LONGi's tandem cell reached 33.9% efficiency, and by June 2024, it had increased to 34.6%. The latest jump to 35.5% efficiency is a testament to the company's relentless pursuit of excellence in solar technology.
The focus on larger device sizes is another notable aspect of LONGi's recent announcements. The company reported efficiencies of 34.3% for a 261cm² tandem cell and 32.2% for a 274cm² tandem cell, demonstrating their ability to maintain high efficiency even at larger scales. This is crucial for the practical implementation of solar technology in various applications.
Furthermore, LONGi's efforts extend beyond individual cells to the development of tandem modules. The company has achieved conversion efficiencies of 31.4% and 29.4% for these modules, with both results independently certified and included in the latest edition of the Solar Cell Efficiency Tables. This certification process adds credibility to LONGi's claims and provides a benchmark for the industry.
The inclusion of LONGi's 35.2%-efficient two-terminal crystalline silicon-perovskite tandem cell in the 68th edition of the Solar Cell Efficiency Tables, compiled by Professor Martin Green at the University of New South Wales, further solidifies the company's position as a leader in solar technology. This recognition highlights the potential impact of LONGi's innovations on the broader solar energy landscape.
In addition to these impressive efficiency numbers, LONGi has also been making strides in other areas of solar technology. The company's hybrid interdigitated back contact (HIBC) cell achieved a conversion efficiency of 28.13%, an improvement on its previous record of 28.04% set in January. This cell was certified by the Institute for Solar Energy Research Hamelin (ISFH) in Germany, adding another layer of validation to LONGi's capabilities.
The recent launch of the Hi-MO 9 Prime module series at Intersolar Europe 2026 further showcases LONGi's versatility and innovation. The module series features a power output of 680W and a module conversion efficiency of 25.2%, indicating a continued focus on practical, high-performance solar solutions. These modules are designed to meet the demands of various applications, from residential to commercial settings.
In conclusion, LONGi's recent achievements in solar cell technology are a testament to the company's dedication to innovation and excellence. With a consistent track record of efficiency improvements, a focus on larger device sizes, and a commitment to practical, high-performance solutions, LONGi is poised to play a significant role in shaping the future of solar energy. As the industry continues to evolve, LONGi's advancements will undoubtedly contribute to the broader goal of making solar energy more accessible and efficient for all.
