26.05%, DAH Solar set a new record of TOPCon cells mass production conversion efficiency!

A new record! The mass production conversion efficiency of DAH Solar's TOPCon cells has reached 26.05%!   The mass production average conversion efficiency of TOPCon cells (PE-poly route) exceeded 26%! On September 3rd, with the superposition application of SE (Selective Emitter) laser doping technology, the mass production average conversion efficiency of DAH Solar TOPCon cells, has reached 26.05%, refreshing the industry record once again, reaching the industry leading level, showing the "DAH speed".     On June 9, DAH Solar and SHENZHEN S.C issued the joint announcement, that DAH Solar's TOPCon cells manufacturing base set the climbing record of 97% yield and 25.4% efficiency in just 23 days (not on SE at that time), which attracted high attention from the whole industry. Subsequently, through the continuous optimization of each technical links and materials, by the end of July, the mass production average conversion efficiency of DAH Solar’s TOPCon cells has reached 25.8%. At the beginning of September, with the equiped of laser SE equipment and technology, the conversion efficiency improved by another 0.25%, creating an industry-leading level by 26.05%.     DAH Solar has always focused on R&D and organization development.Not only in terms of module and PV system product innovation, we have successfully launched the global patent Full-Screen PV module and the world's first integrated PV system SolarUnit, and also forward-looking developand layout of cells technology, with absolute advantages to achieve the full production of TOPCon cells and the high-speed climbing of conversion efficiency and yield. In addition to that, DAH Solar has also precipitated for many years in terms of crystal pulling and slicing technology, laying a good foundation for further improving the layout of industrial integration.

    The Full-Screen PV Power Station Succeed The global patent Full-Screen technology eliminates the 5mm altitude intercept between the module frame and glass. This little change allows rainfalls wash away the dust and reduce the manual cleaning. Without dust shading, the power generation could increase 11.5%! Now, the Full-Screen PV Module series are available. The first Full-Screen PV power station has finished in Taizhou City, Zhejiang Province, China. Mr. Jin is the investor of this project. Mr. Jin is very satisfied with the Full-Screen PV Module. According to Mr. Jin, the Full-Screen PV Module performed significantly. Compare to regular PV modules, the Full-Screen PV Module increased the power generation and decrease the maintenance expenditure.

  • DAH Solar is building 466KW BIPV Project Using Only Full-Screen PV Module in China
    DAH Solar is building 466KW BIPV Project Using Only Full-Screen PV Module in China
    2022-08-02

    DAH Solar is Building 466KW BIPV Project Using Only Full-Screen PV Module in Taizhou City, Zhejiang Province, China This 466KW Low Current Full-Screen PV Module project was starting on April 5th, 2022. This project requires 1012 pieces of Low Current Full-Screen PV Modules. DAH Solar commits to accelerate the solar energy development and provides the warmest services in the worldwide. DAH Solar invent the Full-Screen PV Module and apply the Full-Screen technology to all of our products. The most outstanding products DAH Solar has produced is the Low Current Full-Screen PV Module. This specific product combines all the advantages of the Full-Screen PV Module and the Low Current PV Modules so that it could solve the problem regarding the small-angle installation and create more value for the Power Station. Since the front A-side has no frame, which makes the installation process much easier. Why you need the Full-Screen PV Module? Check the comparison experiment picture below. The regular PV module and the Full-Screen PV Module were placed on the outdoor rooftop at the same time. After few month nature weather in the outdoor environment. You can clear see the rain will wash away the dust on the Full-Screen PV Module. However, the regular PV module formed the dust sedimentation because of the 5mm altitude intercept between the glass and the frame. In this picture, the Full-Screen PV Module has no altitude intercept between glass and frame. This design makes the rain washing away the dust on the Full-Screen PV Module and improve the power generation by 6-15%. DAH Solar not only manufacturing and sales the PV module, but also provide personal PV Module installation design. Since our customers are from all over the world. Different countries has different weather and angle of sunlight. DAH Solar contribute ourselves to provide the warmest customer services. That's why we are responsible to all of our project. For this BIPV project, we recommended the flat installation due to its geographic location and the basic installation condition. Please contact us if you are interested in our Full-Screen PV Module! ( The above project uses DHT-M60X10/FS 460W, contact us if you need quotation.)
