Yingli launches the world's most advanced level of high-efficiency battery integrated power generation efficiency of 24.6%
 |
At Yingli Group's 3rd Technology Innovation Expo, the reporter was informed that Yingli has introduced a new generation of Panda-based high-efficiency N-type single-crystal batteries based on ion implantation technology, as well as the TwinMAX Bifacial series of double-sided power generation dual-glass components. The integrated power generation efficiency is 24.6% is the most advanced level in the world. At present, this series of products has passed stringent reliability verification and mass production. Yingli plans to complete the ion implantation technology upgrade of the existing 800MW Panda battery production line through innovative business models over the next 1-2 years.
Based on the mass production technology upgrade of the first-generation Panda N-type single-crystal double-sided high-efficiency battery production line, the new-generation Panda high-efficiency battery utilizes ion implantation technology to improve battery efficiency. The positive power generation efficiency can reach 21.5% and the backside efficiency can reach more than 95% of the positive. , leading the industry in similar technologies. The front-end power generation of the TwinMAX series PV modules (60 cells) using the new-generation Panda battery can exceed 300W. At the optimized system installation site, the back of the module can contribute up to 30% of the frontal power generation, and the actual generating power exceeds 380W, etc. Efficiency module efficiency exceeds 24%, and successfully applied in China's first PV "leader" demonstration project - 50MW project in the National Advanced Technology Photovoltaic Demonstration Base in Datong coal mining subsidence area in Shanxi Province, which is also the world's largest high-efficiency N-type single crystal. Double glass assembly application project.
Compared to conventional components, the TwinMAX Bifacial series also features double-sided power generation, good low light, strong resistance to corrosive gas erosion such as salt spray, ammonia, and PID (potential potential-induced decay), and excellent durability. , 30 years line nature guarantee and other unique advantages.
According to reports, the “Panda†N-type high-efficiency solar cell independently developed by Yingli is an integration of N-type double-sided cell technology and MWT metal-wrapped cell technology, filling the gap in N-type cell technology and becoming the world's three most efficient solar cells. One of them played a good demonstration role in helping China's photovoltaic industry upgrade its technology.
