LONGi breaks records with 27.09% efficient solar cells

LONGi Green Energy achieves 27.09% efficiency in silicon heterojunction back-contact solar cells, surpassing the 26.81% efficiency record announced in November 2022. The breakthrough, certified by the Institute for Solar Energy Research Hamelin, Germany involves an all-laser patterning process developed in-house, addressing cost concerns associated with photolithography. Notably, the technology reduces reliance on transparent conductive oxide…

LONGi breaks records with 27.09% efficient HBC solar cells

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…
