Route to stable lead-free double perovskites with the electronic structure of CH3NH3PbI3: a case for mixed-cation [Cs/CH3NH3/CH(NH2)2]2InBiBr6

During the past year, halide double perovskites attracted attention as potential lead-free alternatives to Pb-based halide perovskites. However, none of the compounds discovered so far can match the optoelectronic properties of MAPbI3 (MA = CH3NH3). Here we argue that, from the electronic structure...
