LONGi Solar has announced that it has achieved a new monocrystalline silicon PERC world record conversion efficiency using commercial wafer dimensions that exceeds 24 percent for the first time, according to tests carried out by the National Center of Supervision and Inspection on Solar Photovoltaic Product Quality in China.
LONGi Solar's latest breakthrough bifacial (double-sided) PERC solar cells tested by CPVT achieved a conversion efficiency of 24.06 percent. LONGi Solar had previously reported verified record PERC cell conversion efficiencies of 23.6 percent in February 2018.
CPVT tested monocrystalline silicon PERC cell in standard wafer dimension (156.75x156.75mm2) provided by LONGi Solar. The sample cells were measured under standard test conditions for current-voltage characteristics as a function of load.
"LONGi Solar has made great strides in setting world record PERC solar cell conversion efficiencies as we demonstrate the continuing ability to provide high-efficiency products to the global solar market," stated Li Wenxue, President of LONGi Solar. "Our latest record solar cell conversion efficiencies also endorse the success of our R&D investments, which have set the benchmark for the industry in recent years."
"This is the first time that the efficiency of monocrystalline PERC solar cells in commercial dimensions have exceeded 24 percent," remarked Dr. Li Hua, LONGi Solar, Vice President of Cell R&D. "In the last three consecutive years LONGi Solar has developed three generations of 'Hi-MO' products based on PERC technology, which are setting the efficiency and reliability benchmark of high-efficiency PERC technology within the industry."
