Golden Solar New Energy Technology Holdings Limited announced that the group successfully built the first production line of a new generation heterojunction back contact (HBC) cells (HBC cells) this month, and the new generation of HBC cells will become the world's first production line for mass production of HBC cells (The National Advanced Photovoltaic Engineering Research Center jointly built by the Group's strategic partner Gold Stone (Fujian) Energy Company Limited and the Group officially announced a conversion efficiency of 27.42%), as well as the world's only mass production line capable of producing a conversion efficiency greater than 27.0% for the first time, therefore leading the heterojunction technology into back contact cells ("BC cells") mass production. The first generation of heterojunction solar cells ("HJT cells") has developed rapidly in the past two years, and the Directors believe the mass production of the new generation technology of HBC cells indicates that the Group will lead the glorious era of the new generation of BC cells with higher conversion efficiency and lower cost. Meanwhile, the Group also completed the construction of the world's first HBC flexible module mass production line in the middle of this year, which brings to the realization of a vertically integrated high efficiency and low-cost solar industry strategy comprising cast monocrystalline silicon wafers, HBC cells and flexible modules.
