JinkoSolar Holding Co., Ltd., one of the largest and most innovative solar module manufacturers in the world, today announced that the maximum solar conversion efficiency of its large-area N-type monocrystalline silicon solar cells reached 24.79%, and have set a world record for large-size contact-passivated solar cells. This result was independently confirmed by the Institute for Solar Energy Research in Hamelin (ISFH), Germany.
JinkoSolar’s R&D teams of experts in silicon wafer, solar cells and solar modules have made significant breakthroughs in the field of high efficiency and high power of cells and modules for many years.The record-breaking mono-crystalline silicon solar cell was fabricated on a high quality CZ mono-Si substrate, with a practical size of 267.72cm2. Several advanced technologies have been implemented to achieve this new record of 24.79%, including passivating contact technologies, advanced diffusion system, surface passivation and advanced anti-reflection technologies. Series of material upgrade were also integrated into the cell process. The record-breaking mono-crystalline silicon solar cell will be gradually applied for mass production.
“JinkoSolar has reached a key R&D milestone. Our commitment towards technological innovation in silicon material, cell fabrication and module processing technologies has led to multiple world records for the efficiency of solar cells and modules. We are very proud to break the world record with advanced large-area N-type cell in the world. This innovative cell technology also holds the world record for PV module efficiency,” commented Dr. Jin Hao, CTO of JinkoSolar . “We will constantly invest in upgrading technologies to achieve mass production, & to lead the Solar PV Module Technology by providing high efficiency and competitive industrial products for our global customers.”
