As shown in the efficiency roadmap, it is widely believed that the maximum production efficiency of PERC cell is about 23%, therefore, the efficiency record always stays around 23% or below for a long period of time and the related technical research and development personnel are targeted at breaking through 23%.
With 23.26% efficiency, it means that LONGi Solar has surpassed the world record again within 10 days after it released 22.71% efficiency on Oct. 17, moreover, LONGi Solar has broken through the PERC cell efficiency bottleneck (namely, 23%). It not only embodies that LONGi Solar has the world leading level, but also means that monocrystalline PERC technology has the huge potential to improve its efficiency, therefore, the above-mentioned cell is a milestone.
"The new efficiency record is realized by applying the mass-produced cell to optimize its technical means on the basis of the large-area P-type monocrystalline wafers, as a result, we have not only surpassed the world record again, but also enhanced the cell efficiency by a large margin within short period, in such case, the whole industry will reinforce their confidence in the monocrystalline PERC and have high expectations for the future of PERC cell products."
Doctor Li Hua, the Vice President of Research and Development in LONGi Solar Cell, said that, "innovation without limits. LONGi Solar will continue to make great investment in monocrystalline PERC cell, make products by heart and spare no effort to research & development and production terminal to maximize the PERC cell efficiency, import the most advanced research & development achievements into production and bring more benefits for clients."
On the basis of power consumption cost reduction and parity internet, the industry has proposed the increasingly high demands for the cell efficiency in recent two years, in such case, people are paying high attention to the high-efficient cell technology. With the obvious performance and cost advantages, PERC cell has broken through its records continuously, therefore, it means that PERC cell has the excellent power generation capacity and promising application prospect.
Considering that PERC has gained flavor and recognition from the industry, more and more enterprises are willing to work in PERC cell, as a result, monocrystalline PERC technology has developed into the most cost-effective technical route at present. LONGi Solar has focused on enhancing the technology of monocrystalline cell components, such as, it took the initiative in scaling up PERC technology in 2015, until now, the mass production efficiency has reached up to 21.5%.
Under the incessant research & development achievements and efficiency records, it is promising that the large-scale mass production surpasses 22% or 23% efficiency in the near future. All employees have every reason to believe that the mass production efficiency of PERC cell is expected to reach up to 24% in the next five years. Therefore, LONGi Solar will keep its most cost-effective position in the industry.
LONGi Solar is always committed to researching, developing and enhancing the monocrystalline technical route, such as, it always leads the industry development by right of its advanced research & development capacity, capital investment and sci-tech innovation capacity, and takes the leading position in the aspect of monocrystalline PERC cell conversion efficiency.
