Soft and flexible materials called halide perovskites could make solar cells more efficient at significantly less cost, but they are too unstable to use. A Purdue University-led research team has found a way to make halide perovskites stable enough by inhibiting the ion movement that makes them rapidly degrade, unlocking their use for solar panels and electronic devices. A perovskite is made up of components that an engineer can individually replace at the nanometer scale to tune the material's properties.
