LONGi announced on April 11th at its Wuhu base in Anhui Province that its independently developed Hybrid Interdigitated-Back-Contact (HIBC) crystalline silicon solar cell has achieved a groundbreaking photoelectric conversion efficiency of 27.81%, as certified by the authoritative Institute for Solar Energy Research Hamelin (ISFH) in Germany. This achievement pushes the boundaries of monocrystalline silicon photovoltaic cell efficiency to new heights.
In November 2022, LONGi set a world record for crystalline silicon cell conversion efficiency at 26.81%. By May 2024, the company had surpassed this mark, reaching 27.3%, and subsequently achieving 27.4%, 27.52%, and ultimately 27.81%.
The HIBC cell, innovatively developed by LONGi’s Central Research Institute, has achieved dual breakthroughs in optical management and carrier transport efficiency through the reconfiguration of cell structure and material systems, opening up new avenues for enhancing photovoltaic module power density.
True innovation not only breaks technological limits but also anchors long-term value amidst uncertainties. As a global leader in solar energy technology, LONGi drives the photovoltaic industry’s development through independent innovation and original technologies. The BC Generation 2 technology and forward-looking research have achieved continuous breakthroughs, with BC technology now ripe for large-scale development and the Lighthouse Factory advanced manufacturing model being rapidly promoted. This latest world record in monocrystalline silicon photovoltaic cell conversion efficiency not only validates LONGi’s ability to focus on value creation and drive industrial progress but also reflects the company’s ambition to realize global energy transformation and energy equity.
