Recently, PV Tech, an authoritative analysis institution in the PV industry, released the Q2 2025 PV ModuleTech Bankability Report for module manufacturers. LONGi, with its outstanding comprehensive strength, won the highest AAA rating for the 22nd consecutive time.
The PV ModuleTech bankability ratings are derived from a thorough evaluation process that examines manufacturers across several critical dimensions, including value chain strength, production capacity, global shipment profiles, capital expenditure (capex), R&D investment and cash-flow management.
LONGi’s consistent AAA status reflects not only its robust operational metrics but also its dedication to advancing solar technology.
Double Champion: Continuously Pushing Conversion Efficiency to New Heights
As a leading enterprise in the global PV industry, LONGi has always maintained strong technical innovation capabilities.
In both the crystalline silicon and the crystalline silicon-perovskite tandem track, LONGi has continuously refined its R&D, committed to pushing the conversion efficiency to new heights. In April 2025, authenticated by the German Institute for Solar Energy Research Hamelin (ISFH), the photoelectric conversion efficiency of the Hybrid Interdigitated Back Contact (HIBC) technology independently developed by LONGi reached 27.81%, pushing the exploration of the limit of monocrystalline silicon solar cells to a new level.
Almost at the same time, authenticated by the U.S. National Renewable Energy Laboratory (NREL), the conversion efficiency of the crystalline silicon-perovskite tandem solar cell independently developed by LONGi reached 34.85%.
Up to now, LONGi remains the world record holder in both tracks.
True 700W: Leading Module Efficiency into the ‘25%+ Era’
Relying on its profound technology accumulation and advanced intelligent manufacturing advantages, LONGi has firmly deepened its efforts in this field and continued to make breakthroughs since officially announcing the BC technology route in September 2023.
At the SNEC 2025, its newly developed HIBC (Hybrid Interdigitated Back Contact) technology and mass-produced module products were officially released. For the first time, HIBC achieved a power of over 700W based on the standard size 2382mm×1134mm, and the efficiency of mass-produced modules is even close to 26%, comprehensively leading the efficiency of PV modules into the ‘25% + Era’.
LONGi’s continued success is a testament to the trust and recognition it has earned from stakeholders across the global photovoltaic landscape. The company remains dedicated to adapting to market changes and delivering unparalleled value to its customers and partners.
As LONGi looks to the future, it remains focused on its mission of ‘making the best of solar energy to build a green world’,furthering its efforts in technology innovation and the development of sustainable energy solutions.
