Mixed Cation Hybrid Lead Halide Perovskites with Enhanced Performance and Stability

Abstract

Organic and inorganic hybrid perovskites have emerged as a revolutionary optoelectronic semiconductors promising for various applications especially in photovoltaics and light-emitting diodes. Perovskite solar cells demonstrated unprecedented efficiency progress with such short time in the history of photovolatics. More than 20% efficiency and advantages such as easy-to- process and tunable bandgaps has made the perovskite solar cells promising for commercialization. Extending absorption to longer wavelength and addressing the challenge of stability issue in metal halide perovskites have become the most important research focus. Among them, the composition engineering can be a potential solution for metal halide perovskite to further tune band gap and enhance stability. The mixed cation perovskite is one of the most practical and successful strategy for composition engineering. Here, we review recent progress on mixed cation metal halide perovskites including the development of binary, ternary and 2D/3D mixed cation perovskites in chemical synthesis and device performance and stability progress. We also outlook the prospective and challenge for the mixed cation hybrid perovskites.
