JinkoSolar, a China-based global supplier of PV products and ESS solutions, has confirmed a new world record cell efficiency. The achieved n-type TOPCon-based perovskite tandem cell efficiency measured 34.76%. This breakthrough has been certified by the National PV Metric and Testing Center, surpassing the previous record of 34.22%. This achievement marks the company's thirty-second world record for module power and cell efficiency. This result is directly attributed to systematic innovation in perovskite and tandem technologies. Key enhancements include a self-developed high-efficiency N-type TOPCon bottom cell for improved performance. Additional improvements involve perovskite bottom interface defect passivation to enhance charge transport capabilities. Novel perovskite crystallization techniques and optimized vertical charge transport strategies further contributed to the breakthrough, according to JinkoSolar. Recently, JinkoSolar has signed a 300 MW Tiger Neo 3.0 supply deal with DMM in Japan.
