On October 27, 2017, Longji Leye received a test report from the National Center for Photovoltaic Product Quality Supervision and Inspection (CPVT). The report shows that the maximum conversion efficiency of Longji Leye Single Crystal PERC Battery has reached 23.26%.
According to the efficiency roadmap, the industry generally believes that the PERC battery can be mass-produced at a limit of around 23%. For a long time before, the efficiency record has remained at a level below 23%. Breaking through 23% has become the goal of industry technology R&D personnel. This time, 23.26% is not only Longji Leye, after releasing the world record of 22.71% on October 17th for 10 days, once again set a world record, and broke through the 23% efficiency bottleneck of PERC batteries previously considered by the industry. Longji Leye's technological leadership in the industry, on the other hand, also proves that the single crystal PERC technology has great potential for efficiency improvement and is of great significance.
“The new efficiency record is also based on large-area P-type single-crystal silicon wafers, and the use of mass-produced battery process technology to optimize the realization. This time not only once again set a world record, but also in a short period of time has greatly improved, This further strengthened the confidence of the industry in single crystal PERC and looked forward to the future of PERC battery products.†Dr. Li Hua, vice president of research and development of Longji Leye battery, said, “There is no limit to innovation, and Longji Leye will continue to remain in the future. PERC Batteries invests heavily in the concept of making good products. We continue to work hard on R&D and production, strive to explore the higher levels of PERC battery efficiency, and introduce the most advanced R&D results into production as soon as possible, bringing more value to our customers. ."
In the past two years, based on the desire to reduce the cost of electricity and achieve a low-cost Internet access, the industry has placed ever-increasing demands on battery efficiency, and the degree of attention for high-efficiency battery technology has also increased. PERC battery has obvious performance and cost advantages, and the continuous breakthrough record also proves the excellent power generation capacity and wide application prospect of PERC battery. Therefore, PERC is favored and recognized by the industry. More and more companies have joined the PERC camp, and the single crystal PERC technology has become the most cost-effective battery technology route. Longji Leye focused on improving the technology of single-crystal battery components and has taken the lead in the scale-up of PERC technology in 2015. Currently, the efficiency of quantitative production has reached 21.5%. With the continuous development of R&D achievements and efficiency records, mass production breakthroughs of 22% and 23% are just around the corner! We have every reason to believe that the mass production efficiency of PERC technology in the next five years is expected to reach 24%, and continue to maintain the status of the most cost-effective technology in the industry.
