China's photovoltaic industry has gone from lagging behind to leading through continuous technological breakthroughs. Looking back at the development of the photovoltaic industry, Zhong Baoshen pointed out that an industry may not have scale, but it cannot be without technology; We can experience lows, but we cannot lose innovation. Technological innovation is the primary productive force for breaking internal competition, and the ultimate mission of the photovoltaic industry is to ensure safety, reliability, and reduce the cost of electricity per kilowatt hour. As long as there are still people who believe that 'technology is the first principle', Chinese photovoltaics will always have a future. The 8 technologies showcased this time are just the tip of the iceberg of Longji's "technology forest".



中国光伏从落后到领先，靠的是持续的技术突破。回顾光伏产业发展，钟宝申指出，一个产业可以没有规模，但不能没有技术；可以经历低谷，但不能失去创新。科技创新是打破内卷的第一生产力，安全可靠、降低度电成本是光伏行业的终极使命。只要还有人相信"技术才是第一性原理"，中国光伏就永远有未来。而此次亮相的8项技术，不过是隆基"技术森林"露出水面的冰山一角。




ACM Technology: Multiple Innovations Breakthrough Bottlenecks. Recently, the Longi Green Energy ACM (Nanoalloy Matrix Contact) battery project officially went into mass production at the Xixian production base, becoming a key milestone in the large-scale implementation of Longi's new battery technology. ACM technology is an innovative grid line technology independently developed by LONGi, which is a major innovation in materials and processes. It uses patented nano alloy materials and a new matrix contact technology to achieve efficiency and reliability upgrades for battery and component products. At the material level, ACM combines the excellent properties of multiple metals and achieves a leap in the conductivity of gate lines through scientific proportioning and surface nano level oxidation resistance technology - the resistance value is only half of that of conventional TOPCon, and the conductive channel is equivalent to expanding from a "two lane" to a high-speed "ten lane", greatly improving transmission efficiency. At the process level, matrix contact technology achieves precise zoning between the contact layer and the transmission layer: the current collection layer reduces composite losses with the minimum contact area, while the current transmission layer ensures more uniform and efficient current output, allowing professionals to do their job.



ACM技术：多重创新突破瓶颈，近日，隆基绿能ACM（纳米合金矩阵式接触）电池项目在西咸生产基地正式量产，成为隆基新型电池技术规模化落地的关键里程碑。ACM技术是隆基自主研发的一项创新栅线技术，是材料和工艺方面的重大创新，采用专利授权的纳米合金材料和全新的矩阵式接触技术，实现了电池及组件产品的效率与可靠性升级。在材料层面，ACM结合多种金属的优异特性，通过科学配比与表面纳米级抗氧化技术，实现了栅线导电性能的跃升——电阻值仅为常规TOPCon的一半，导电通道相当于从"双车道"扩建为高速"十车道"，传输效率大幅提升。在工艺层面，矩阵式接触技术实现了接触层与传输层的精准分区：电流收集层以最小接触面积减少复合损失，电流传输层则确保更均匀、更高效的电流输出，"让专业的人干专业的事"。




This breakthrough brings three core values: in terms of high efficiency, smaller resistance, matrix contact technology combined with innovative passivation technology bring higher efficiency and power - the conversion efficiency for mass production is increased by 0.2% -0.3%, with a maximum power of 672W; in terms of high reliability, the welding area at the main gate position is doubled, combined with the unique "one" welding structure of BC batteries, which basically eliminates the risks of virtual welding and gate breakage; Nanoscale anti-oxidation technology can effectively prevent the oxidation caused by the contact of air, water vapor and metal to achieve comprehensive anti-aging and better power generation in the whole life cycle; In terms of high power generation capacity, ACM technology brings customers more stable and abundant power output thanks to better conductivity and higher component power.



这项突破带来三大核心价值：高效率方面，更小的电阻、矩阵式接触工艺叠加创新钝化技术，带来更高效率与更高功率——量产转换效率提升0.2%-0.3%，最高功率672W；高可靠性方面，主栅位置焊接面积增加一倍，叠加BC电池特有的"一"字型焊接结构，基本解除了虚焊、断栅风险；纳米级抗氧化技术有效阻止空气、水汽与金属接触产生的氧化，实现全面抗老化，全生命周期发电更出色；高发电能力方面，得益于更优的导电性能与更高的组件功率，ACM技术为客户带来更稳定、更充沛的发电输出。




Integrated conductive backplate: Remove solder strips and replace "points" with "surfaces". Industry data shows that the line loss generated on the solder strips accounts for more than 60% of the total component line loss. Traditional components have internal solder strips that exceed 400 meters. The battery cells are connected in series through more than 15000 solder joints, each of which is a stress concentration point. Under long-term thermal expansion, contraction, and mechanical loads, it is easy to cause hidden cracks, desoldering, power attenuation, and even component failure. Welding tape - a connection method that has been in use for twenty years - is becoming a bottleneck that restricts the improvement of component reliability. The integrated conductive backplane technology released by LONGi this time innovatively eliminates traditional solder strips and replaces traditional "point contact" soldering with metal foil "full area surface contact", fundamentally reconstructing the circuit architecture of components. Compared with traditional solder strips, the current transmission cross-sectional area is increased by more than 85%, the stress of the battery cell is reduced by 60%, and the water vapor transmission rate is reduced by 90%. At the same time, due to the reflection effect of the metal foil, the long wave light passing through the silicon wafer is reflected back to the battery for secondary absorption, which can further increase the power of the single component by 3-5 watts. One technology solves problems from the 'core', while another technology solves problems from the 'body'. The combination of ACM and integrated conductive backplate technology has elevated the reliability of components to a whole new level. Multiple innovations have been launched to build a complete "technology forest". In addition to the two heavyweight technologies of ACM and integrated conductive backplate, Longfor has also released multiple innovative achievements, constructing a complete "technology forest" from battery efficiency to component reliability to system intelligence. The stacking technology adopts a seamless arrangement of 0.4mm battery cell edges that are precisely overlapped, converting the original 2-3mm ineffective gap into an effective power generation area, and increasing the effective power generation area of the component by 2%.



一体化导电背板：取消焊带，以"面"代"点"，行业数据显示，在焊带上产生的线损占到整个组件线损的60%以上，传统组件内部焊带超过了400米，通过15000多个焊点将电池片串联，每个焊点都是应力集中点，在长期热胀冷缩和机械载荷下容易引发隐裂、脱焊，进而导致功率衰减甚至组件失效。焊带——这一沿用了二十年的连接方式——正在成为制约组件可靠性提升的瓶颈。本次隆基发布的一体化导电背板技术，创新性取消了传统焊带，用金属箔"全域面接触"替代传统"点接触"焊接，从根本上重构了组件的电路架构。相比传统焊带，电流传输截面积提升85%以上，电池片应力降低60%，水汽通过率降低90%，同时由于金属箔的反射作用，穿透硅片的长波光线被反射回电池进行二次吸收，可以使单块组件功率再提升3-5瓦。一项技术从"芯"里解决问题，一项技术从"体"上解决问题。ACM与一体化导电背板两项技术叠加，将组件的可靠性提升到了全新高度。多项创新齐发构建完整"技术森林"，除ACM和一体化导电背板两大重磅技术外，隆基本次还集中发布了多项创新成果，构建起从电池效率到组件可靠性再到系统智能化的完整"技术森林"。叠片技术采用0.4mm电池片边缘精密重叠的无缝排布方式，将原本2-3mm的无效间隙转化为有效发电区域，组件有效发电面积提升2%。




By relying on the 40 micron thin metal foil and low-temperature interconnection process of the integrated conductive backplate, we have successfully overcome the problems of stress concentration and easy fragmentation in traditional laminated processes. The hidden busbar technology abandons the traditional front exposed busbar structure, eliminates the front shading area, and increases the effective light receiving area of the component by 1.1%. Replacing traditional thick solder strips over 250 microns with 40 micron thin metal foil eliminates extrusion damage from the source. The temperature controlled alloy interconnection technology fully utilizes the advantages of the front non grid line of BC batteries, relying on a high-precision visual positioning system to achieve micrometer level interconnection layout accuracy. Combined with low-temperature fusion technology, it effectively releases interface thermal stress and ensures long-term reliability. Intelligent component technology independently configures a maximum power point tracking module for each component, completely eliminating the "barrel effect" in occlusion and multi-directional scenes, and increasing power generation by 5% -30%. Simultaneously equipped with active and passive dual-mode fast shutdown function, the component automatically shuts down in milliseconds in case of abnormal conditions, and the power station shuts down quickly in case of abnormal conditions. Within 20 seconds, the high voltage on the DC side is reduced to within 30V safe voltage, which not only eliminates the risk of fire, but also meets the requirements of shutdown regulations, ensuring the safety of the fire rescue environment. In addition, the intelligent component technology is equipped with the "Longi Intelligent Photovoltaic" APP, which can real-time grasp the operation data of the power plant component level, achieve rapid positioning of individual components, and improve operation and maintenance efficiency.



依托一体化导电背板的40微米薄金属箔和低温互联工艺，一举攻克传统叠片工艺应力集中、易碎片的难题。隐藏汇流条技术摒弃传统正面外露汇流条结构，消除正面遮光区域，组件有效受光面积再增加1.1%。配合40微米薄金属箔替代250微米以上传统厚焊带，从源头消除挤压损伤。控温合金互联技术充分发挥BC电池正面无栅线的优势，依托高精度视觉定位系统实现微米级互联排布精度，配合低温熔合工艺有效释放界面热应力，保障长期可靠性。智能组件技术为每块组件独立配置最大功率点追踪模块，彻底消除遮挡、多朝向场景下的"木桶效应"，发电量提升5%-30%。同时具备主被动双模式快速关断功能，组件异常毫秒级自动关断，电站异常快速关断，20秒内将直流侧高压降至30V安全电压以内，不仅可消除火灾风险，还能满足关断法规要求，保障消防救援环境安全。另外，智能组件技术搭载"隆基智能光伏"APP，实时掌握电站组件级的运行数据，可实现单块组件快速定位，提高运维效率。




This technology has obtained T Ü V S Ü D certification for "smart photovoltaic modules" in 2025. Currently, the technology is mature and will hold a global product launch event for smart modules in Brazil on August 25th. It is expected to achieve mass production and delivery in October.



该技术已于2025年获得TÜV南德"智能光伏组件"认证，目前该技术已然成熟，将于8月25日在巴西举办智能组件全球产品发布会，预计10月可实现量产交付。




LONGi One OS technology is a new generation of intelligent comprehensive energy management platform developed by LONGi for the integration of photovoltaic storage and charging scenarios, equipped with AI intelligent agents. It can access market-oriented electricity price data, integrate multi-dimensional parameters such as photovoltaic power generation prediction, load prediction, weather forecast, and user historical electricity load. AI outputs the optimal charging and discharging strategy every 15 minutes to maximize the return on energy storage assets. The platform is equipped with self-developed AI intelligent agents, which can provide AI usage guidance, fault diagnosis, and early warning, reducing the operational threshold by 90%. Li Zhenguo said that in the future, we can also freely combine several technology trees from this technology forest to create a product that can solve customer pain points. It is worth mentioning that if these technologies are converged and stacked on standard components, the power of the 2382mm × 1134mm standard size component can directly exceed 690W, and the efficiency can reach 25.54%. At this press conference, Longi simultaneously announced its latest scientific breakthrough: certified by the European Solar Energy Testing Institute (ESTI), Longi's independently developed crystalline silicon perovskite stacked solar cell achieved a conversion efficiency of 35.5%, once again breaking the world record for perovskite stacked cell efficiency and providing solid technical verification for the next generation of photovoltaic technology. BC route: Based on the laws of physics, all technological innovations released this time are based on Longi's firm layout of BC technology route.



LONGi One OS技术是隆基面向光储充荷一体化场景、搭载AI智能体的新一代智慧综合能源管理平台，可接入市场化电价数据，融合光伏发电预测、负荷预测、天气预报、用户历史用电负荷等多维参数，AI每15分钟输出最优充放电策略，实现储能资产收益最大化。平台搭载自研AI智能体，可实现AI使用指导、故障诊断及预警，让运维门槛降低90%。李振国表示，未来我们也可以从这个技术森林中，随意组合几棵科技树，就是一个能解决客户痛点的产品。值得一提的是，若这些技术在标准组件上汇聚叠加，2382mm×1134mm的标准尺寸组件功率可直接突破690W，效率达到25.54%。此次发布会，隆基同步公布了最新科研突破：经欧洲太阳能测试机构（ESTI）认证，隆基自主研发的晶硅-钙钛矿叠层太阳电池转换效率达到35.5%，再次刷新钙钛矿叠层电池效率世界纪录，为下一代光伏技术路线提供了坚实的技术验证。BC路线：基于物理定律的战略笃定，本次发布的所有技术创新，均基于隆基坚定布局的BC技术路线。




BC has no obstruction on the front and is a perfect photovoltaic cell structure. Shen Wenzhong pointed out that the theoretical efficiency limit of BC can reach 29.1%, which not only has higher efficiency, but also has significant advantages in reliability, aesthetics, and adaptability to application scenarios. Professor Shen Wenzhong emphasized that the structural advantages of BC technology endow it with stronger technological scalability and innovation carrying capacity. In his view, silver paste substitution is the only way for the sustainable development of the industry, and the bottleneck of perovskite stability is still difficult to break through in the short term. The industry is simultaneously exploring alternative top battery materials such as crystalline silicon stacks, reserving an 8 to 10 year development window for BC batteries. The systematic implementation of Longi's "Technology Forest" concept is driving the industry from single point innovation to full chain reconstruction. Based on this judgment, Longi firmly chose the BC technology route many years ago and continued to deepen its cultivation. By the end of 2025, Longi has obtained 510 BC related patent authorizations, including 330 invention patents. Deep technical reserves support large-scale implementation, and it is expected that by the end of 2026, Longi BC components will ship nearly 100GW globally. More than 30 manufacturers have laid out BC technology, and BC has become the mainstream technology, which has become an industry consensus. three



"BC正面无遮挡，是一个完美的光伏电池结构。"沈文忠指出，BC的理论效率极限可以达到29.1%，不仅效率更高，而且在可靠性、美观度、应用场景适应性等方面均具有显著优势。沈文忠教授强调，BC技术的结构优势赋予其更强的技术延展性与创新承载力。在他看来，银浆替代已是行业可持续发展的必由之路，而钙钛矿稳定性瓶颈短期仍难突破，业内正同步探索晶硅叠层等备选顶电池材料，为BC电池预留出8至10年的发展窗口。隆基"技术森林"理念的系统性落地，正推动行业从单点创新迈向全链条重构。基于这一判断，隆基多年前便坚定选择BC技术路线并持续深耕。截至2025年底，隆基取得BC相关专利授权510件，其中发明专利330件。深厚技术储备支撑规模化落地，预计2026年底，隆基BC组件全球出货近100GW。布局BC技术的厂商已超过30家，BC成为主流技术已成行业共识。三




Anti Pro component: The first landing result of "Technology Forest". At the press conference, Niu Yanyan, President of Longi Green Energy Distributed China, officially released the Hi MO X10 Three Anti Pro component. This is the first technology product in Longi's "Technology Forest" to achieve mass production and landing, equipped with omnidirectional anti dust technology and ACM technology. In response to customer feedback on pain points, the Longi Hi MO X10 Three proof Pro component adopts L-shaped alloy edging and high-strength buckle frame (mortise and tenon structure), achieving four core upgrades: omnidirectional anti dust accumulation, anti dent, wind resistance, and operational efficiency. In terms of preventing dust accumulation, both the long and short edges of the frame are flush with the glass, and can be installed horizontally or vertically to prevent dust accumulation.



防Pro组件："技术森林"首个落地成果，发布会现场，隆基绿能分布式中国区总裁牛燕燕正式发布Hi-MO X10三防Pro组件，这是隆基"技术森林"中首个实现量产落地的技术产品，搭载全向防积灰技术和ACM技术。针对客户反馈的痛点问题，隆基Hi-MO X10三防Pro组件采用L型合金包边搭配高强度卡扣框（榫卯结构），实现全向防积灰、抗凹陷、抗风性、运装效率四大核心升级。在防积灰方面，长短边边框均与玻璃齐平，横装、竖装均可防积灰。




In terms of anti indentation, the buckle frame provides greater support for the middle of the component. According to the actual measurement of the Ningxia Binggou project, the anti indentation performance of the Three Defense Pro component is more than 67% better than that of the oversized version component. In terms of wind resistance, the product has passed dynamic load tests of ± 1500Pa and over 60000 times (conventional components are tested at 1000Pa and 20000 times), and its tear resistance has passed 50000 vibration tests (conventional components are tested at 6000 times), which is 7 times higher than that of conventional components. In terms of transportation and installation efficiency, each pallet can accommodate 41 pieces (conventional 36 pieces). Based on a 17.5m flatbed truck calculation, the shipping cost per megawatt will be reduced by 2300 yuan, and the installation efficiency of T-bolts will be improved by 30%. In addition, the Longi Hi MO X10 three proof Pro component has a power of 670W and an efficiency of 24.7%. It has anti fire and anti blocking functions, with a first-year attenuation of 1% and a linear attenuation of 0.35%. The product is guaranteed for 15 years and the power is guaranteed for 30 years. Horizontal, vertical, and flexible installation can prevent dust accumulation no matter how you install it! "Niu Yanyan announced that the Longi Hi MO X10 Three proof Pro component has achieved mass production and can be delivered from today. The technology forest continues to thrive, from breaking through material bottlenecks with ACM to reconstructing the underlying logic of integrated conductive backboards; From stacking and hiding busbars to every millimeter of efficiency, to intelligent components and LONGi One OS giving optical storage systems a "brain" - each technology released by LONGi this time is not an isolated existence, but an organic whole that supports and grows together in the "technology forest". Li Zhenguo said that the products that everyone can buy today were tested in large quantities two or three years ago; The technology we are hearing about today was initiated for research and development five to ten years ago; The unnamed technologies in the Longi laboratory are preparing for the next five or ten years. The significance of the 'technology forest' lies not only in its current fruits, but also in its ability to sustain growth.



在抗凹陷方面，卡扣框为组件中部提供更大力度支撑，据宁夏兵沟项目实测显示，三防Pro组件较超大版型组件抗凹陷性能领先67%以上。在抗风性方面，产品通过±1500Pa、6万次以上动载测试（常规组件为1000Pa、2万次），耐撕裂性能通过5万次激振测试（常规组件6000次），耐撕裂性能较常规组件提升7倍。在运装效率方面，每托容纳41块（常规36块），以17.5m板车测算，单兆瓦运费直降2300元，T型螺栓安装效率提升30%。此外，隆基Hi-MO X10三防Pro组件功率达670W，效率24.7%，具备防起火、防遮挡功能，首年衰减1%，线性衰减0.35%，产品质保15年，功率质保30年。"横装、竖装、随心装，怎么装都能防积灰！"牛燕燕宣布，隆基Hi-MO X10三防Pro组件已实现量产，即日起可交付。技术森林 生生不息，从ACM突破材料瓶颈，到一体化导电背板重构组件底层逻辑；从叠片、隐藏汇流条向每一毫米要效率，到智能组件、LONGi One OS让光储系统拥有"大脑"——隆基此次发布的每一项技术，都不是孤立的存在，而是"技术森林"中相互支撑、协同生长的有机整体。李振国表示，今天大家能买到的产品，是我们两三年前就开展放量验证的；今天大家听到的技术，是我们五至十年前就开始立项攻关的；隆基实验室里那些还没有命名的技术，正在为下一个五年、十年做准备。"技术森林"的意义，不仅在于当下的果实，更在于持续生长的能力。




The industry cycle fluctuates, but the tree of technology remains evergreen. What Longi's "Technology Forest" relies on is not the leadership of a single technology, but the innovative ability of continuous iteration and self growth. When each technology tree has deep roots and lush leaves, supporting each other, it constitutes the most solid endogenous force for enterprises to cross the cycle.



行业周期起伏，但技术之树常青。隆基"技术森林"所倚重的，不是某一项技术的领先，而是持续迭代、自我生长的创新能力。当一棵棵科技树根深叶茂、相互支撑，便构成了企业穿越周期最坚实的内生力量。
