Auda Optoelectronics won the world's first batch of N-type TOPCon double-glass module desert photovoltaic certification > 0BB technology certification from TÜV Rheinland

2025,06,12

On the second day of the SNEC exhibition, Ouda Optoelectronics held a grand certification ceremony at the booth site, and officially obtained the world's first batch of N-type TOPCon double-glass module desert photovoltaic certification and 0BB technology certification from TÜV Rheinland, marking a major breakthrough in photovoltaic technology innovation and product quality.With its abundant sunlight resources and vast space, desert areas are becoming an important layout area for large-scale photovoltaic power generation. However, extreme conditions such as high ultraviolet rays, high temperatures, temperature differences between day and night, and sand and dust erosion in desert environments pose severe challenges to the long-term reliability of PV modules. TÜV Rheinland launched the desert PV module standard, which clarifies the key technical requirements and test methods of modules in desert environments, helping enterprises optimize product design and improve the weather resistance and economy of modules.The N-type TOPCon double-glass module of Oda Optoelectronics has passed the rigorous 3.5-month test of TÜV Rheinland, becoming one of the first companies in the world to obtain this certification. This not only proves the technical strength of Oda Optoelectronics in the field of desert photovoltaic modules, but also lays a solid quality foundation for the development of the global desert photovoltaic market. Mr. Li Weichun, Vice President of TÜV Rheinland Global Power Electronics Product Service and Vice President of Solar & Commercial Product Service Greater China, said: "TÜV Rheinland has always paid attention to the pain points of the industry, relying on global experience and technological advantages to promote the industry to higher standards. The certification of Ouda Optoelectronics is the result of the joint efforts of both parties in photovoltaic technology innovation and quality improvement. ”By eliminating the traditional busbar design, only the fine busbar (secondary busbar) is retained, and the welding strip or polymer film embedded with metal wire is used to collect current and connect the cells in series in the module link, so as to achieve a "busbar-less" structure. This technology has significant advantages in reducing costs and increasing efficiency: the consumption of silver paste is reduced by about 30%, the amount of welding strip is reduced by 10%, the amount of adhesive film is reduced by 30%, and the thin silicon wafer is supported to 100μm, further reducing the cost; At the same time, the main grid is eliminated to expand the light-receiving area, and the dense solder joints shorten the current transmission path, which significantly improves the photoelectric conversion efficiency and reliability of the module.With its deep accumulation in photovoltaic technology R&D and manufacturing, Ouda Optoelectronics took the lead in realizing the commercial application of 0BB technology and obtained the authoritative certification of TÜV Rheinland. Ms. Zhang Hongyan, Chairman of Ningbo Ouda Optoelectronics Co., Ltd., said at the certification ceremony: "The successful application of 0BB technology not only enhances the competitiveness of Ouda Optoelectronics products, but also provides strong support for the technological upgrading and sustainable development of the photovoltaic industry. We will continue to increase R&D investment and promote the application of more innovative technologies. "Obtaining the world's first batch of N-type TOPCon double-glass module desert photovoltaic certification and 0BB technology certification from TÜV Rheinland is an important milestone for Auda Optoelectronics in photovoltaic technology innovation and product quality improvement. In the future, Ouda Optoelectronics will continue to work with TÜV Rheinland to jointly promote the high-quality development of the photovoltaic industry and contribute to the global renewable energy industry.
