We present a strategy to simultaneously enhance the efficiency and stability of perovskite solar cells by introducing a new pseudo-halide additive based on formamidinium methanesulfonate (FAMeSf). The optimal additive concentration of 2 mol% leads to improved efficiency of over 21% and superior stab...
