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."
PV CellTech 2019 will explain the key issues driving solar cell production changes over the next 2-3 years, and what type of advanced cell types will gain market-share. Featuring the CTOs and heads of R&D from leading cell producers, equipment/material suppliers and research institutes, PV CellTech will again prove to be the must-attend solar cell manufacturing event of the year.
