"introducing magnesium into perovskite structure as non-toxic substitute for lead... based on MAPbxMg1-xCl2I using 1-step anti-solvent approach resulted in tetragonal perovskite phase with efficient solar energy conversion... instead of expensive metal cathodes, the ARCI team's innovation uses simple architecture that is cost-effective, robust, along with rapid response and recovery times, all achieved without bias"
