Longi P-Type, Indium-Free HJT Solar Cells

Longi P-Type, Indium-Free HJT Solar Cells : Breakthrough in Photovoltaic Conversion Efficiency

On M6 wafers, Longi claimed to have obtained efficiency ratings of 26.56% for a gallium-doped, p-type heterojunction (HJT) solar cell and 26.09% for an indium-free HJT cell. The data have been verified by Germany’s Institute for Solar Energy Research in Hamelin (ISFH). Meanwhile, Longi also revealed that it has achieved power conversion efficiencies in mass production. For the same solar cell, the Chinese PV module manufacturer reported
