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.

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.

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.

Advanced： - Advanced efficiency: HPBC2.0, the most efficient solar technology currently in mass production, with cell efficiency exceeding 26.6%, Hi-MO X10 module efficiency reached 24.8%, power generation per unit area increased by more than 5% compared with TOPCon. - Advanced technology: Based on BC cell platform, it is superimposed with three core technologies of TaiRay wafer, bipolar hybrid passivation and 0BB zero busbar. It has nearly 200 patented technologies，resulting in stronger power generation performance. Valued-added： Hi-MO X10 modules are 30W more powerful than TOPCon - As a result, each module generates more than 60 kWh of additional electricity per year, generating an additional income of CNY42. Over 30 years, the total additional income will be CNY1,255. - Each module requires an additional investment of less than CNY100, which can be paid back in less than two and a half years. Additional investment can bring 10 times the income. （The above data is calculated in Xi ‘an, China as an example） Aesthetic： - No grid line on the front, pure flawless black, showing the noble temperament. - Similar to the appearance of LCD large-screen, matching the multi-scene design concept, to achieve perfect integration with the building. Safe： - Unique soft breakdown design, using the bypass diode effect, avoiding hot spots due to localized overheating when shaded, eliminating fire hazards. - High-strength TaiRay wafers are stacked with one-line flat welding tape technology, which avoids folding and connecting the front and back sides of the welding tape and greatly reduces the risk of hidden cracks in wafers. - More heightened full-scene test, to ensure the product safety and reliability of the whole life cycle, provide 30 years power warranty.

Taking the 72-cell version as an example, the module size is 2382*1134*30mm, the maximum power of the module is 670W, the highest efficiency is 24.8%, the first-year degradation is 1%, the linear degradation is 0.35%, and the power temperature coefficient is -0.26%/℃. The mainstream mass-produced power is an average of 30W higher than the market's TOPCon products, making it the module with the highest mass production efficiency globally.

①Ultimate Safety The unique soft breakdown design of Hi-MO X10 can significantly reduce the hot spot temperature under shading, preventing local overheating, reducing it by more than 28% compared to conventional cells, and reducing the risk of module failure. At the same time, its low operating temperature and high-density packaging perform excellently under rigorous testing, with superior resistance to UV, humidity, and thermal cycling compared to TOPCon cells. Moreover, Hi-MO X10 has system-level impact resistance and hidden crack performance, with its high-thickness TaiRay silicon wafers + full back welding, comprehensively enhancing the resistance to hidden cracks. ②Higher Power Generation Hi-MO X10 has the highest mass production power of 670W, with a module efficiency of 24.8%, making it the module with the highest mass production efficiency currently available. Its mass production power is 30W higher than the mainstream power of TOPCon. The innovative anti- shading feature can reduce power loss by more than 70% under various shading conditions compared to TOPCon. Its 0BB structure enhances the potential for cell efficiency, allowing the module power to increase by about 5W. At the same time, both the power temperature coefficient and degradation performance have been greatly optimized, improving to -0.26%/℃ and linear degradation of 0.35% respectively. Overall, under the limited installation area of distributed systems, it can bring greater installation capacity, higher power output, and more economic benefits to customers. The global typical regional power generation simulation of Hi-MO X10 shows an increase of 8.7% compared to TOPCon. ③Minimalist Aesthetics Hi-MO X10 continues the minimalist aesthetic design of BC cells, with no grid lines on the front, a simple and elegant appearance, and a harmonious blend with architecture, highlighting the beauty of quality life. After adopting the 0BB structure, compared to traditional non-BC products, such as TOPCon modules, it not only achieves "no grid lines on the front" but also further achieves "no busbars on the back." In addition to enhancing cell efficiency, it also further optimizes the aesthetics of the back side and can increase the cell's bifaciality, providing greater potential for the development of future double-sided cells and module products.
