Record efficiency of 26.81% for large silicon solar cells
Chinese solar cell developer Longi Green Energy Technology is claiming a new record efficiency for its full sized monocrystalline silicon wafers at 26.81%. This is certified by the Institut für Solarenergieforschung in Hameln (ISFH) and exceed the previous record of 26.7% in 2017 for a heterojunction (HJT) cell. This combines a a crystalline silicon cell […]
