Solar cell efficiency records have continued to fall after LONGi toasted breakthroughs in both high-efficiency p-type solar cells and commercial heterojunction (HJ) cells.
LONGi revealed today that its Cell R&D Center had achieved a new record cell efficiency of a p-type monocrystalline bifacial TOPCon solar cell of 25.02%, the first time a p-type cell had recorded a conversion efficiency in excess of 25%.
The record was validated by the Institute for Solar Energy Research (ISFH) in Hamelin, Germany, which also confirmed LONGi’s record for its commercial-sized monocrystalline HJ solar cell produced by LONGi’s New Technology R&D Center.

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%.

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.
