Lead-based perovskites efficiently turn light into electricity but they also present some major drawbacks: the most efficient materials are not very stable, while lead is a toxic element. Scientists are studying alternatives to lead-based perovskites. It is very important to investigate in situ how lead-free perovskite crystals form and how the crystal structure affects the functioning of the solar cells.
