Probing the local electronic structure in metal halide perovskites through cobalt substitution (Small Methods 6/2023)

Journal article

Inside Front Cover
In article number 2300095, Hesjedal and co-workers demonstrate that the substitution of Co2+ ions into the halide perovskite imparts magnetic behavior to the material while maintaining photovoltaic performance. We utilize the Co2+ ions (shown as robots) themselves as probes to sense the local electronic environment of lead in the perovskite, thereby opening the substitution gateway for developing novel functional perovskite materials and devices for future technologies.
