Since the emergence of perovskite as an exceptional light absorbing material, it has made significant advancements in enhancing the efficiency of solar cells. Building upon this foundation, the reconfiguration of internal optical properties within perovskite holds the promise of further improving efficiency. We investigated the influence of metallic aluminum triangular nanostructures on absorption rates. Our findings indicate that the incorporation of stacked aluminum triangular nanostructures into perovskite thin films, along with controlled adjustments in the side length, can significantly enhance absorption rates. In conclusion, comparative tests revealed a remarkable 51% increase in the solar spectrum absorption rate for single layer perovskite thin film photovoltaic cells with a thickness of 200 nm.
