Researchers from the National University of Singapore (NUS) have made a significant breakthrough in solar cell technology. Their newly developed triple-junction perovskite/Si tandem solar cell achieved a certified world-record power conversion efficiency of 27.1%. This was achieved by incorporating cyanate, a novel material, into the perovskite layer of the cell. This addition stabilizes the structure and reduces energy loss, leading to higher voltage and overall efficiency. This new design overcomes limitations of traditional multi-junction cells, paving the way for future advancements in perovskite solar cell technology, with a theoretical efficiency limit exceeding 50%.
