LONGi reaches 25.47% efficiency with latest HJT solar cells

Chinese solar panel manufacturer LONGi announced it has reached 25.47% efficiency with its gallium-doped p-type HJT silicon solar cells using the M6 (166-mm) wafer size. The record was confirmed by the Institute for Solar Energy Research in Hamelin (ISFH).

LONGi’s R&D team has developed a p-type wafer processing solution for HJT cells and combined it with interface passivation technology to achieve a Voc of 747.6 mV for p-HJT cells. It should be noted that the processing of the low-cost p-HJT cell solution applied in this record has not yet been fully optimized and LONGi is convinced that this technology route still has great potential for further development.

Meyer Burger’s commercial line of HJT solar panels reach 21.8% efficiency.
