China-based JinkoSolar has announced that its practical sized (245.83cm2) p-type multi-crystalline silicon solar cells reached the world’s highest conversion efficiency of 22.04%. The company notes this is the second time JinkoSolar broke this world record since October 2016.
JinkoSolar says its record-breaking multi-crystalline silicon solar cell was manufactured on a high-quality 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 new world record was independently confirmed by Fraunhofer ISE Germany and broke JinkoSolar’s previous record of 21.63% one year ago.
“This is the first time that conversion efficiency for p-type mc-Si PERC cells exceeded the 22 percent efficiency mark, which I believe will serve as a guideline developing higher-efficiency products,” comments 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.”
