JinkoSolar’s P-type multi-crystalline silicon solar cell has reached the world’s highest conversion efficiency of 22.04%, the second time JinkoSolar has broken this world record since October 2016.
The cell was manufactured on a boron-doped mc-Si substrate. Advanced texturing, passivation and anti-LID technologies were integrated into the passivated emitter rear contact (PERC) structure to achieve the new 22.04% world record.
The record was confirmed by Fraunhofer ISE Germany and broke JinkoSolar’s previous record of 21.63%.
“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,” said JinkoSolar vice-president Dr Jin Hao.
“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.”
