Longi Sets New Record with 34.85% Efficiency in Tandem Solar Cells, Paving the Way for a Solar Revolution

34.85% Efficiency Achievement! LONGi’s Tandem Solar Cells Reach New Heights, Signaling a Solar Revolution Ahead!
On April 16, 2025, in an era where renewable energy is gaining significant attention, LONGi Green Energy has once again captured global interest! Recently, LONGi announced that its latest development, the crystalline silicon-perovskite tandem solar cell, has achieved an astounding 34.85% conversion efficiency, certified by the National Renewable Energy Laboratory (NREL). This remarkable achievement not only sets a new world record in the field but also provides a significant boost to the advancement of clean energy.
The crystalline silicon-perovskite tandem solar cell is considered a next-generation ultra-efficient solar cell, with a theoretical efficiency limit of 43%. This indicates that future solar cells could potentially be more efficient than the commonly used monocrystalline solar cells, which have a Shockley-Queisser limit efficiency of 33.7%. LONGi’s tandem cell team began a series of breakthroughs in November 2023, initially raising the efficiency to 33.9% within six months. This was followed by another leap to 34.6% in June 2024, ultimately achieving the current milestone of 34.85% through persistent efforts and unwavering determination.
Even more exciting, LONGi has also announced at its Wuhu base in Anhui that its developed Heterojunction Back Contact (HIBC) crystalline silicon solar cells have reached a photoelectric conversion efficiency of 27.81%. This further solidifies LONGi’s leadership in both monocrystalline solar cells and crystalline silicon-perovskite tandem cells. Such impressive results showcase LONGi’s vast potential in high-efficiency battery technology and underscore China’s progress and commitment in the global green transition.
From a technical perspective, the core advantage of the crystalline silicon-perovskite tandem structure lies in its high light absorption capacity and effective spectral utilization within the cells. This technology, if widely adopted, could lower solar power generation costs and enhance light conversion efficiency, injecting new vitality into the photovoltaic industry. As technology continues to advance, solar power generation is poised to become a mainstream choice for households and industries, contributing significantly to sustainable development.
The era of green energy has arrived. LONGi’s innovative breakthrough is not only a victory for technology but also a reflection of humanity’s pursuit of environmental ideals. The implications extend beyond a transformation in battery technology; they prompt us to reconsider our future energy approaches. At this pivotal moment, it is essential to reflect on how we can promote technological advancement while safeguarding our planet, opting for clearer renewable energy solutions.
In the days to come, LONGi’s journey to lead the solar revolution will undoubtedly inspire more enterprises to pursue sustainable development. If you are interested in the prospects of solar and other renewable energies, LONGi’s success could serve as a starting point for exploring this field. Through this small step, we may anticipate the entire industry reaching greater technical heights in the future, providing a solid foundation for achieving global clean energy goals.
In conclusion, a 34.85% battery efficiency is not just a number; it signals the beginning of a new chapter for LONGi Green Energy. In an age of rapid technological advancements, who will take up the baton to further explore the unknown? Solar energy may become the hero of the future!
