Halide Segregation in Mixed-Halide Perovskites: Influence of A-Site Cations
[Image: see text] Mixed-halide perovskites offer bandgap tunability essential for multijunction solar cells; however, a detrimental halide segregation under light is often observed. Here we combine simultaneous in situ photoluminescence and X-ray diffraction measurements to demonstrate clear differe...
