Halide perovskites is the collective name for a group of materials that are considered very promising and cost-effective for flexible and lightweight solar cells and various optical applications, such as LED lighting. This is because many of these materials absorb and emit light in an extremely efficient way. However, perovskite materials may degrade quickly, and in order to know how best to apply these materials, a deeper understanding is required of why this happens and how the material functions.
