Dual-Site additive mediated Crystallization Strategy for Homogenized FA-Cs Based Perovskite Solar Cells

Key Points

• The new crystallization strategy improves the stability of perovskite solar cells significantly, with a focus on mixed A-site materials.
• Key evidence shows enhanced efficiency and minimized cation segregation, leading to better performance of solar cells.
• This approach employs a dual-site additive crystallization method to optimize the perovskite lattice structure for higher stability.
• The findings indicate that this strategy could support wider use of perovskite photovoltaics in commercial applications.
