Due to their exceptional photovoltaic properties, metal halide perovskites (MHPs) are extensively studied for potential applications in solar cells. In recent years, the power conversion efficiencies of MHPs-based cells rapidly increased from initial few \% towards more than 25\,\% single-junction devices. Therefore, also taking into account low costs and ease manufacturing, have become fastest...
