Cover Picture: Metal halide perovskite (MHP) materials have attracted a lot of interest because of their potential for use in solar cells, photonic devices, and X-ray detectors. However, we still don't know many things about their properties before we can use them on a large scale. MHP materials can change when they are used, and it's important to understand what happens on a very small scale, which requires advanced tools and in situ and operando experiments. One problem with MHP materials is that they can change when they are exposed to light and other conditions, and it's very complicated to study these changes. In this study, we looked at the damage caused by X-rays on MHP using multiple synchrotron radiation techniques. We found that high doses of X-rays caused noticeable changes in the material, such as the loss of certain components, changes in the shape of the sample, and changes in optical properties. These changes are caused by a combination of radiolysis and sputtering processes. We also found that controlling the dose of X-rays and the conditions around the material can help reduce this damage.
