Picture this: just days after achieving a groundbreaking world record with an awe-inspiring 25.82% efficiency for its HJT solar cells, LONGi Solar has unleashed yet another triumph, a new world record boasting an astonishing 26.30% efficiency.
Hold onto your solar hats because this isn't just any record; it signifies the zenith of efficiency for a Front-Back Contact (FBC) solar cell, solidifying LONGi's dominance in the solar energy arena. The validation of this exceptional feat took place at none other than the renowned German Institut für Solarenergieforschung (ISFH), the bastion of solar excellence.
But that's not all – the fill factor (FF) of the certified cells has soared to unprecedented heights, breaching the 86% threshold and reaching an astronomical 86.59%. This not only represents a monumental achievement in itself but also secures the world's highest level for silicon cells. How did they achieve this feat, you ask? LONGi's brilliant Research and Development team have conjured up a groundbreaking process that significantly reduces contact resistance at the interface, elevating the FF and boosting a cell's current density to a staggering 40.49mA/cm² on an M6 9BB cell.
Dive into the technical marvels, and you'll discover that the cells responsible for these groundbreaking records were meticulously optimized. The microcrystalline N window layer underwent a transformation to further enhance current density, and a novel intrinsic layer structure was developed, elevating passivation performance and pushing the Voc up by a jaw-dropping 2mV. To top it all off, LONGi's team applied a completely indium-free TCO process, pushing the boundaries of solar cell technology.
But wait, there's more! These groundbreaking cells were certified by ISFH with an efficiency of more than 25%, providing not just a record but a tangible path for cost reduction in HJT industrialization. From 25.26% to 25.82% and now to an unprecedented 26.30%, LONGi has achieved the extraordinary feat of setting HJT cell efficiency world records not once, not twice, but three times in just six months!
Hold your applause because LONGi doesn't stop there. Their N-type and P-Type TOPCon cells have also clinched the title of the world's highest conversion efficiency, boasting an impressive 25.21% and 25.19% respectively. The sheer audacity of these achievements places LONGi at the forefront of cutting-edge solar technology.
In the eyes of LONGi, the relentless pursuit of research and development in HJT solar cell technology is not just a commitment; it's a mission to lead the global energy transformation through technological innovation. These three world records, achieved within a mere six months, not only underscore LONGi's position as a trailblazer in innovative high-efficiency solar cell technology but also affirm their vision to propel the sustainable and rapid development of the global PV industry. Brace yourselves because the future of solar energy is now, and LONGi Solar is leading the charge with an unparalleled display of brilliance!
