On 7 May Longi Green Energy Technology Co announced that the company has broken another world-record for silicon solar cell efficiency only 4 months after it last set such a world-record. As certified by Germany’s Institute for Solar Energy Research Hamelin, new silicon hetero-junction back-contact (HBC) solar cells designed by Longi have achieved an efficiency of 27.30 % under laboratory conditions. The new record was announced at a celebratory event where Longi also unveiled a new product, the Hi-MO 9 silicon solar module featuring a conversion efficiency of up to 24.43 %.
The announcement represented the 17th time that the company has set a world-record in solar cell efficiency since April 2021, firmly establishing it as a leader in crystalline silicon photovoltaics – the company is now the world-record holder both for efficiency in crystalline silicon solar cells and for efficiency in crystalline silicon-perovskite cells – in November it announced that it had set a world record in the efficiency of crystalline silicon-perovskite tandem solar cells of 33.9%.
The Hi-MO 9 module
On the same day, 7 May, Longi launched its new, flagship Hi-MO 9 module. This is a solar module with capabilities of up to 660 W, based on 2nd generation hybrid passivated back contact (HPBC) cell technology and the TaiRay wafer, a silicon wafer launched by Lonki in March this year. The Hi-MO 9 module exhibits a conversion efficiency up to 24.43%, and is designed to excel in a range of tough environments, including mountain and desert locations).
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.
