This talk will focus on one class of energy conversion and storage materials based on perovskites. Using density functional theory and molecular dynamics simulation, we have analyzed the source of the instability of the structure and show how this can be overcome by replacing halogens with cluster ions, without compromising their electronic or optical properties. Similarly, we will report that antiperovskites which have been recently used as solid electrolytes in Li-ion batteries can be modified to increase their superionic conductivity. A new class of solids with clusters as building blocks can usher a new era in materials science where rational design can lead to materials with unprecedented properties.
