Longi claims world’s highest efficiency for p-type, indium-free HJT solar cells
Longi has revealed that it has achieved power conversion efficiencies in mass production of 26.56% for a gallium-doped p-type HJT solar cell and 26.09% for an indium-free HJT cell, both based on M6 full-size monocrystalline silicon wafers. The results have been confirmed by ISFH. “Addressing the long-term pain point of HJT cells, Longi’s R&D team focused
