Abstract
High-entropy is a hot topic in materials research but has not fully entered the halide perovskites (HPs) field. Aiming to achieve this goal, we synthesized and characterized penta-organic A-site cation HP solid solutions. Preliminary results on the structure and stability demonstrate the potential for future developments.
