A family of compounds known as perovskites, which can be made into thin films with many promising electronic and optical properties, has been a hot research topic in recent years. But although these materials could potentially be highly useful in applications such as solar cells, some limitations still hamper their efficiency and consistency. Now, a team of researchers say they have made significant inroads toward understanding a process for improving perovskites' performance, by modifying the material using intense light.
