LONGi Green Energy achieves a world record 27.09% efficiency in crystalline silicon heterojunction back-contact solar cells. The breakthrough, independently developed using an all-laser patterning process, surpasses the previous 26.81% record. Additionally, their HBC cells boast reduced usage of transparent conductive oxide layers, with the 27.09% efficiency cell utilizing only 1/5 of the indium compared to traditional bifacial heterojunction solar cells.
