LONGi Sets New Record In Silicon Solar Cell Efficiency

LONGi Green Energy Technology Co. announced that the company has broken another world record for silicon solar cell efficiency only four months after it last set a world record in this area on May 7. As certified by Germany’s Institute for Solar Energy Research Hamelin (ISFH), the new silicon heterojunction back-contact (HBC) solar cells designed by LONGi have reached an efficiency of 27.30% under laboratory conditions.

The new record was announced at a celebratory event where they also unveiled a new product, the Hi-MO 9. Guests at this event included LONGi’s founder and president, Li Zhenguo, Vice President Dennis She, Chief Scientist Dr. Xu Xixiang, and client representatives from across the globe.

The announcement represents the 17^th time that the company has set a world record in solar cell efficiency since April 2021, it said in a media statement. 

The company is now the twin world record holder both for efficiency in crystalline silicon solar cells and for efficiency in crystalline silicon-perovskite tandem solar cells. In November 2023, LONGi announced that the company had set an additional world record in the efficiency of crystalline silicon-perovskite tandem solar cells of 33.9%.

At a celebratory event held in Madrid, Spain, on the evening of the 7th of May, LONGi launched its all-new, flagship Hi-MO 9 module. The Hi-MO 9 is a solar module with capabilities of up to 660W, based on the 2nd generation Hybrid Passivated Back Contact (HPBC) solar cell technology and the TaiRay wafer, an silicon wafer launched by LONGi in March 2024, and the Hi-MO 9 module boasts a conversion efficiency up to 24.43%, built to excel in a range of tough environments (including lakes, mountains, and deserts).

Dennis She, Vice President of LONGi Green Energy Technology Co., said: “Our new Hi-MO 9 module allows world-leading power generation and outmatches other technologies on the market in an equal land-use scenario. What’s more, it retains this performance throughout its life, as the module is designed to the highest standards of reliability. Power plant owners can rest assured that a plant built from the Hi-MO 9 module will help them make the most efficient use of their land and get the most value out of sunlight.”

The panels will be produced at the company’s Jiaxing Production Base which has been recognized by the World Economic Forum as a Global Lighthouse Factory, a group of factories that have been judged to be accelerating the adoption of Fourth Industrial Revolution technologies in manufacturing.
