November 9 (Solar) – Chinese solar products maker Longi Solar said it has renewed for the fourth time in 2018 its world record for PERC module efficiency, now reaching 20.83%.
The 20.83% conversion efficiency of the company's 60-cell monocrystalline PERC module has been confirmed by testing and certification provider TUV-SUD.
According to Longi Solar vice president Lv Jun, the new record further demonstrates the development headroom of PERC. "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," Lv Jun said.
The company noted that between April 2017 and February 2018, it improved its PERC cell efficiency five times, crossing 23% for mass production efficiency. All of its cell production lines will be upgraded to PERC.
