Description:
Article An imbalance in I/Pb stoichiometry is thought to lead to defects in metal halide films. Here, Zhang et al . show that the addition of hypophosphorous acid in the precursor solution can significantly improve the film quality and enhance the photoluminescence intensity, leading to improved photovoltaic devices.
