Life and Death of Mixed Metal Halide Perovskites : Mechanism and Consequences of Light Induced Halide Segregation in MAPb(I,Br)3
Metal halide perovskites have attracted immense scientific interest due to their outstanding optoelectronic properties over a widebandgap range. Applications cover a wide range of optoelectronic devices from solar cells, LEDs and lasers to X-ray detectors.[1,2] Particularly in combination with existing silicon technology, perovskite-silicon tandem solar cells, which achieve power conver-sion effic
