Further gains were reported less than two weeks later when the company reported a conversion efficiency of 23.26%, breaching the industry-accepted limit of 23% for a mass produced PERC cell.

Li Wenxue, President of LONGi Solar said, “The new world record for the conversion efficiency of LONGi Solar's monocrystalline PERC module is the first major breakthrough in module efficiency. Through continuous technological innovations, we will bring more efficient monocrystalline module products to the market to help PV investors earn more power generation benefits and contribute to the cause for clean water and blue sky.”
