Photophysical Properties of Metal Halide Perovskite Thin Films

Hybrid organic-inorganic halide perovskites have become the most promising materials in the field of photovoltaics. In just four years the power conversion efficiency of solar cells based on hybrid perovskites has rapidly increased from an initial promising value of 9% to over 22%. Their extraordinary properties, including high carrier mobility, low carrier recombination rates, and the tunable spectral absorption range are attributed to the unique electronic properties of these materials. The application field of hybrid perovskites has quickly expanded in terms of types of materials by substituting one or more of the organic or inorganic ions in one of the most studied perovskites, to obtain the metal halide perovskites AMX
