TUV-SUD has verified LONGi Solar’s P-type monocrystalline PERC module to have a conversion efficiency of 20.41%, a new industry record.

‘Silicon Module Super League’ (SMSL) member LONGi Solar, a subsidiary of LONGI Green Energy Technology, the largest monocrystalline wafer producer in the world has reported that TUV-SUD has verified its P-type monocrystalline PERC module to have a conversion efficiency of 20.41%, a new industry record.

PV Tech previously reported that LONGi Solar had reached a world record conversion efficiency for a P-type monocrystalline PERC solar cell, certified by CPVT in China at 22.17% in April 2017 and in October the same year had Fraunhofer ISE CalLab in Germany verify other cells at a new record efficiency of 22.71%.
