Scientists discovered how to control a material’s properties and stability to develop next-generation solar cells based on newly discovered hybrid perovskites (atomic structure shown above). Simulations revealed that hybrid perovskites could be viewed as super-alkali halides. The schematic illustrates a hybrid perovskite structure where the super halogens are the blue tetrahedrons, the metal atoms are green, and the alkali cation is in the middle (gray structure with pink and black atoms).

Lead-free, more efficient solar cells and other optoelectronics devices will likely be based on a family of materials known as hybrid perovskites...
