The vast majority of high-performance perovskite solar cells (PSCs) are based on multi-cation mixed-anion compositions incorporating methylammonium (MA) and bromide (Br). Nevertheless, the thermal instability of MA and the tendency of mixed halide compositions to phase segregate limit the long-term stability of PSCs.
