LONGi Solar rewrites the world record of PERC module conversion efficiency at 20.83%
XI'AN, China, Nov. 9, 2018 /PRNewswire-AsiaNet/ --

On November 8th, LONGi Solar announced that tests conducted by TUV-SUD, an 
independent third-party test institute, proved the photoelectric conversion 
efficiency of LONGi Solar's 60-cell PERC module reached 20.83%, breaking the 
monocrystalline PERC module efficiency world record. This is the fourth time in 
2018 that LONGi Solar had renewed its world record of module efficiency.

Photoelectric conversion efficiency has gained a lot of attention in the 
development of photovoltaic technology as it directly corelates to lowering 
photovoltaic LCOE. Improvements in module conversion efficiency are linked to 
lower cost. Meeting customers' satisfaction with optimal module efficiency and 
system efficiency is a key issue that needs to be addressed in the R&D of 
high-efficiency cells and modules. 

LONGi Solar has continuously focused on the improvement of conversion 
efficiency, strengthened its R&D and leads the industry in strategic layout and 
technical gains of high-efficiency products. In particular, its high-efficiency 
cell and module technology flourishes with innovations such as new bifacial, 
half-cut-cell and shingled-cell technology. In the three consecutive years from 
2016 to 2018, three generations of Hi-MO products based on PERC technology were 
launched, leading the trend of PERC efficiency improvements in the industry. 

Dr. Lv Jun, Vice President of LONGi Solar, said: "LONGi Solar has been 
exploring the value of PERC products in recent years and keeps pushing the 
boundaries of PERC technology so as to further improve the cost performance. 
The new breakthrough of module conversion efficiency this time further proves 
the development headroom of PERC. We firmly believe PERC will play greater 
technical possibility in the next three years to effectively improve power 
generation efficiency and reliability of photovoltaic system, lower LCOE and 
bring higher benefits for customers."

The breakthroughs in high-efficiency modules cannot be separated from efficient 
cell technology. From April 2017 to February 2018, LONGi Solar had improved its 
PERC cell efficiency five times, breaking the 23% mass production efficiency. 
Currently, all cell production lines of LONGi Solar will be upgraded to PERC to 
fully meet the demand of the global market for next generation high-efficiency 
PERC products.
