JinkoSolar Holding Co., Ltd. (NYSE: JKS), a leading solar module manufacturer, saw its stock soar 5.91% in the pre-market trading session on Monday. This surge can be attributed to the company's significant breakthrough in the development of its N-type TOPCon-based perovskite tandem solar cell.
According to JinkoSolar's announcement, the company's perovskite tandem solar cell achieved a record conversion efficiency of 33.84%, surpassing its previous record of 33.24%. This remarkable achievement was independently tested by the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences.
The record-breaking perovskite tandem solar cell utilizes JinkoSolar's N-type high-efficiency monocrystalline TOPCon solar cell as the bottom cell, enhanced by innovations such as full-area passivated contact technology, perovskite interfacial defect passivation technology, and bulk defect passivation technology. This breakthrough highlights the compatibility of TOPCon as a mainstream solar cell technology with the next-generation perovskite/silicon tandem cell technology, paving the way for new possibilities in the future development of the photovoltaic industry.
