Wednesday, 02 June 2021 LONGi has set new cell efficiency records for N- and P-type TOPcon and HJT. The company announced in April its record of 25.09% for N-Type TOPCon solar cell efficiency and, one month later, testing at the Institute for Solar Energy Research (ISFH) in Hamelin, Germany, has confirmed that the conversion efficiency of N-type monocrystalline bifacial TOPCon solar cells developed at LONGi’s Cell R&D Center has now reached 25.21%. Courtesy of LONGi The Cell R&D Center has also achieved an innovative breakthrough in high-efficiency P-type monocrystalline solar cell product technology. Again tested by ISFH (Calibration Mark: 001592), the efficiency of a commercial size P-type monocrystalline bifacial TOPCon solar cell exceeded 25% for the first time, setting a world record of 25.02% in the process.
