Academia Sinica and Taiwan universities develop 31% efficient solar cells

Academia Sinica, along with Cheng Kung University, Tsinghua University, and Mingzhi University of Science and Technology, has developed tandem perovskite/silicon solar cells with over 31% efficiency. This surpasses the 22-24% efficiency of current silicon-based cells and represents nearly 50% improvement compared to earlier solar installations. The innovation aims to enhance solar power generation efficiency without requiring additional land, supporting Taiwan’s energy transition. The tandem cells use perovskite thin films and silicon layers to broaden light absorption and increase performance. Current results are based on small-area modules, showcasing Taiwan’s capacity to develop and commercialize the technology. Academia Sinica plans to optimize production processes and collaborate with industry to scale up. This project is part of the "net-zero 5 arrows" strategy, focusing on advancing solar photovoltaics and supporting sustainability goals.
