Leading ‘Silicon Module Super League’ (SMSL) member JinkoSolar has reported a record solar cell efficiency of 22.04% for a P-type multicrystalline PERC (Passivated Emitter Rear Cell), using its practical sized (245.83cm2) wafer.
The company said that the record conversion efficiency was achieved on a high quality boron doped mc-Si substrate. Advanced texturing, passivation and anti-LID technologies were integrated into the PERC cell.
The new world record was said to have been independently confirmed by Fraunhofer ISE, breaking JinkoSolar’s previous record of 21.63% set in 2016.
“This is the first time that conversion efficiency for P-type mc-Si PERC cells exceeded the 22% efficiency mark which I believe will serve as a guideline developing higher efficiency products,” commented by Dr. Jin Hao, Vice President of JinkoSolar. “The entire manufacturing chain is comprised of low-cost industrial processes and will be gradually transferred into mass production. Leveraging our high-efficiency solar cells, we will continue to develop advanced manufacturing techniques to reduce the cost of PV products.”
