Today, TCL Zhonghuan held a ceremony for the official launch of its new generation BC high-efficiency modules at its Tianjin base, marking the company's transition from leading BC technology research and development into a new phase of large-scale mass production. The newly launched modules are centered on a dual-native core barrier of native technology and native materials, achieving a maximum module efficiency of 25.2% and a peak power output of 680W. They are designed to comprehensively cover applications in ground-mounted power stations and commercial/industrial scenarios, redefining the standards for high-efficiency photovoltaic products with pure, native BC technology.

Technological Breakthrough: Leveraging Wafer Advantages to Reach New Heights in BC Technology TCL Zhonghuan's BC modules adhere to a native BC positioning. Distinguished from other BC product manufacturers in the industry, TCL Zhonghuan possesses three irreplicable advantages in the BC field: 1. Proprietary Foundational Support: Ownership of over 1,600 foundational BC patents, providing a deep technological foundation. 2. Dedicated Wafer Supply: Exclusive supply of Zhonghuan BC wafers, ensuring high compatibility between materials and processes. 3. Extensive Technical Heritage: Over 30 years of R&D accumulation, achieving a TBC cell efficiency exceeding 27% and a low temperature coefficient of -0.26%/°C. All products in this mass production batch utilize silicon wafers produced in-house by TCL Zhonghuan. As the absolute global leader in photovoltaic wafers, TCL Zhonghuan's dedicated BC wafer series employs TS002 high-efficiency, low-carbon wafer technology, featuring minority carrier lifetimes exceeding 1000μs, which better meets the demands for high conversion efficiency in BC product cells. Furthermore, for BC cells, TCL Zhonghuan has adopted a novel cell-level anti-hotspot design, effectively reducing hotspot temperatures by up to 50°C compared to conventional modules, with a low-light performance coefficient exceeding 95%.

Defining a New Benchmark for High-Efficiency Modules with Dual Excellence in Efficiency and Quality The newly launched TCL Zhonghuan high-efficiency N-type BC modules not only incorporate the company's self-developed N-type wafers and advanced BC cell technology but also feature several breakthrough technical characteristics: - Ultra-high Conversion Efficiency: Mass production conversion efficiency reaches 25.2%, with a maximum module output power of 680W, matching the power level of mainstream BC products in the market. The products also feature fire resistance, shading resistance, and dust accumulation resistance ("three-proof" characteristics) and come with a 30-year linear power warranty and a 15-year product materials warranty. - Excellent Bifacial Power Generation Performance: Bifaciality is increased to 80%±5%, with significant backside power generation gains. - Outstanding Reliability Performance: Potential Induced Degradation (PID) attenuation is controlled within 1% throughout the product lifecycle. The modules have passed rigorous certifications from authoritative domestic and international institutions, including TÜV Rheinland and the National Photovoltaic Quality Inspection Center. - Superior Aesthetic Performance: The front side has no grid line shading, presenting a pure, uniform all-black appearance, perfectly suited for Building-Integrated Photovoltaics (BIPV) and high-end residential photovoltaic applications. - Full-Scenario Adaptability: Widely applicable in various scenarios such as large-scale ground-mounted power stations and commercial/industrial distributed generation, effectively reducing the levelized cost of electricity (LCOE) over the lifecycle and creating higher investment returns for customers.

Dual-Native BC: A BC Pioneer Redefines BC Once More As the global pioneer and continuous leader in BC (Back Contact) technology, leveraging over forty years of semiconductor materials expertise and nearly four decades of experience in the photovoltaic industry, TCL Zhonghuan has established an industry-unique "Dual-Native BC" technology system. This system inherits the technical lineage of deep involvement in the BC field since 1985 while integrating TCL Zhonghuan's native advantages in areas like 210mm large-size wafers, N-type materials, and intelligent manufacturing. With the dual foundation of "technological source + industrial base," it redefines the developmental boundaries and application value of BC technology. Regarding technical heritage and patent reserves, TCL Zhonghuan possesses the world's most complete and core BC intellectual property system. As the first company globally to achieve commercial mass production of IBC cells (in 2004), and after over two decades of technological iteration, TCL Zhonghuan holds more than 1,600 globally authorized BC patents, covering the entire industry chain from crystal growth and cell structure to process manufacturing and module packaging, establishing a comprehensive patent protection network in major global photovoltaic markets. Looking ahead, TCL Zhonghuan will continue to advance hand-in-hand with all its customers and partners. With firmer conviction and an unwavering commitment to innovation, the company will maintain its leading position in industry technology, contributing Zhonghuan's strength to achieving global carbon neutrality goals.
