LONGi sets new record for p-type HJT silicon solar cell efficiency

XI'AN,China,March 30,2022 -- LONGi has announced a new efficiency breakthrough for its Gallium-doped p-type HJT silicon solar cell. The new world record conversion efficiency of 25.47% for large-size p-type cells was achieved using a mass production process on full-size (M6,274.3cm²) monocrystalline silicon wafers,the result,validated in testing carried out at the Institute for Solar Energy Research in Hamelin (ISFH),further demonstrating the feasibility of low-cost HJT mass production technology.

LONGi sets new record for p-type HJT silicon solar cell efficiency

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.

As a world-leading solar technology company,LONGi remains at the forefront of innovation in cutting-edge PV technologies. In 2021,the company established an impressive series of efficiency records,with its n-type TOPCon,p-type TOPCon and n-type HJT cells achieving conversion efficiencies of 25.21%,25.19% and 26.30% respectively.

Going forward,LONGi will continue to increase its investment in technology R&D and focus on customer value creation,in order to accelerate global energy transformation and contribute to the achievement of carbon reduction targets with its high-efficiency products continuing to deliver lower LCOE.
