FAQ

Q: What is the Hi-MO X10 product?
 

A: The LONGi Hi-MO X10 is a premium product built on the revolutionary HPBC 2.0 cell technology. It leads in terms of power generation performance, reliability, and customer benefits, while also meeting the needs of distributed market segments. It is divided into four series:Explorer, Scientist, Guardian and  Artist, making it the preferred high-value product for the global distributed market.

Q: What is the HPBC 2.0 cell?
 

A:  HPBC 2.0 is the abbreviation for the second generation of Hybrid Passivation Back Contact cell technology, independently developed and named by LONGi. HPBC 2.0 continues the excellent genes of the HPBC 1.0 cell technology, based on a high- end BC technology platform, primarily characterized by the absence of grid lines on the front side. It is an innovative BC cell technology independently researched and developed by LONGi, based on a comprehensive optimization of cell substrates, hybrid passivation, and process technologies. Its performance, reliability, and functionality have been significantly enhanced, showing a clear generational difference from the mainstream market's general cells. It is the masterpiece of BC cell technology and also declares that the era of BC has truly arrived. We can define it with a simple formula: HPBC 2.0 = BC x Bipolar Hybrid Passivation x TaiRay Wafer x 0BB Structure.

Q: What are the differences between HPBC 2.0 cell technology and 1.0?
 

A:  HPBC 2.0 continues the excellent genes of the HPBC 1.0 cell technology and achieves key leaps at three technical levels, which have led to a leapfrogging in cell performance. Its mass production efficiency has broken through 26.6%, making it the highest mass production efficiency cell technology currently available. In terms of silicon substrates, HPBC 2.0 cell technology utilizes LONGi's own high-quality TaiRay N-type silicon wafers, which optimize and enhance the cell's degradation, efficiency potential, and resistance concentration. In terms of passivation technology, HPBC 2.0 cell further upgrades and optimizes the comprehensive hybrid passivation based on 1.0, achieving Bipolar Hybrid Passivation, which can effectively reduce recombination and increase the open-circuit voltage of the cell. In terms of process technology, HPBC 2.0 innovatively develops the 0BB (Zero Busbar) structure, reducing current transmission distance by 6.5% and enhancing the cell's efficiency potential, which can increase the module power by about 5W. At the same time, it employs self-developed high-precision laser etching processes and insulating material printing, effectively ensuring insulation and eliminating the risk of leakage, thereby enhancing the electrical transmission capability.
