Wide-bandgap perovskite with homogeneous crystallization and suppressed halogen segregation for efficient perovskite-organic tandem solar cells
The differences in crystallization and migration barriers of iodide and bromide within wide-bandgap perovskite result in inhomogeneous crystallization and halogen-phase segregation, limiting photovoltaic device performance. Here we report a sequential regulation engineering to synchronously homogenize crystallization a...
