Chinese solar panel maker Longi Solar said it has set a record for the efficiency of a bifacial solar cell. Test results on its product, called a bifacial passivated emitter rear contact (PERC) cell, were backed by China’s National Center of Supervision and Inspection on Solar Photovoltaic Products Quality. Longi said the rear side of its bifacial module achieved about 75% of the front side, compared with an industry standard of 82.15%.
