Lead-free perovskite solar panel materials

Simple Science Summary Just over ten years ago, scientists discovered a new, promising material that could convert light into electricity: metal-halide perovskite. The first solar cell perovskites contained lead, which is toxic. Soon, perovskites were developed that were based on tin, but these were not very stable. A few years ago, scientists at the University of Groningen demonstrated that adding
