October 3 (Renewables Now) - Chinese solar manufacturer JinkoSolar Holding Co Ltd (NYSE:JKS) said on Monday its p-type multi-crystalline silicon (multi-Si) solar cells have achieved a conversion efficiency of 22.04%, the highest reached so far.
The Chinese firm claims that this is the highest efficiency achieved in the world for practical sized 245.83 sq cm (38.1 sq in) p-type multi-Si passivated emitter rear contact (PERC) cells.
The result has been confirmed by the Fraunhofer ISE in Germany. It was achieved with a multi-Si cell made on a high-quality boron doped multi-Si substrate, having PERC structure integrated with advanced texturing, passivation and anti-light induced degradation (LID) technologies.
"The entire manufacturing chain is comprised of low-cost industrial processes and will be gradually transferred into mass production,” JinkoSolar’s vice president Jin Hao.
Last October, JinkoSolar said it had achieved a conversion efficiency for p-type multi-Si PERC cell of 21.63%.
