BEIJING, Oct. 23, 2017 /PRNewswire=KYODO JBN/ --

LONGi Green Energy Technology Co., Ltd. announced today that Fraunhofer ISE

CalLab of Germany certified a photovoltaic conversion efficiency of 22.71% on

the company's monocrystalline PERC cell, which is a new world record for this

cell type.

As the industry's leading manufacturer of high efficient monocrystalline

products, LONGi has always been committed to the improvement of the

monocrystalline technology. Since its founding in 2001, the company has built

and relied upon its own R&D capabilities. LONGi continues to lead the industry

in scientific advancement and technological innovation, as demonstrated by the

company's progress in the conversion efficiency of its PERC cell:

-In April 2017, LONGi Solar's 100MW pilot cell line achieved maximum efficiency

of 22.17% in mass production (certified by CPVT);

-At the end of August, LONGi Solar improved the efficiency to 22.43%.

This recent breakthrough in conversion efficiency is LONGi's latest and most

important technology R&D achievement to-date. It also marks the arrival of a

Chinese enterprise as a leading-edge photovoltaic producer.

In 2015, the China top-runner project acquainted users with monocrystalline

PERC modules. Since then, PERC's huge potential has increasingly attracted the

industry's attention. With this breakthrough in PERC cell efficiency, LONGi has

confirmed the outstanding power generation capability and broad application

prospects of monocrystalline PERC technology.

Dr. Li Hua, Vice President of Cell R&D of LONGi Solar, said: "Based on

large-area, P-type monocrystalline silicon wafer, we are able to employ mass

production compatible cell process technology and able to realize a conversion

efficiency of 22.71%. This greatly enhances the entire industry's confidence in

P-type monocrystalline cell. With continued R&D optimization, we believe the

monocrystalline PERC cell can reach a conversion efficiency of greater than

23.0% in the near future."

LONGi Solar plans to introduce the 22.0% efficient PERC cell technology into

the production line at the end of 2017, allowing the company to deliver Top

Runner-compliant products with leading edge technical standards. LONGi's module

power rating will achieve 340W-345W for a 60-cell  format by 2018.

LONGi continues to strengthen its technology platform. In the first half of

2017, it has reinvested over 7% of its revenue back into R&D. This ratio is

among the top in the industry. By its keen focus on technological advancements,

LONGi aims to make solar a bigger part of the global energy mix.
