WebThe recent discovery of lead-free halide double perovskites with band gaps in the visible represents an important step forward in the design of environmentally friendly perovskite solar cells. Within this new family of semiconductors, Cs2BiAgCl6 and Cs2BiAgBr6 are stable compounds crystallizing in the elpasolite structure. Following the recent … WebThe fundamental photophysics involved in the doping effect of zero-dimensional (0D) lead-free tin-halide perovskite (Cs4SnX6, X = Br and I), especially the dynamics of self-trapped excitons (STEs), is crucial for their practical applications. Here, we proposed the use of Mn2+ doping to realize efficient emis Journal of Materials Chemistry C HOT Papers
