Abstract

Abstract: Three‐dimensional (3 D) perovskite has attracted a lot of attention owing to its success in photovoltaic (PV) solar cells. However, one of its major crucial issues lies in its stability, which has limited its commercialization. An important property of organic–inorganic perovskite is the possibility of forming a layered material by using long organic cations that do not fit into the octahedral cage. These long organic cations act as a "barrier" that "caps" 3 D perovskite to form the layered material. Controlling the number of perovskite layers could provide a confined structure with chemical and physical properties that are different from those of 3 D perovskite. This opens up a whole new batch of interesting materials with huge potential for optoelectronic applications. This Minireview presents the synthesis, properties, and structural orientation of low‐dimensional perovskite. It also discusses the progress of low‐dimensional perovskite in PV solar cells, which, to date, have performance comparable to that of 3 D perovskite but with enhanced stability. Finally, the use of low‐dimensional perovskite in light‐emitting diodes (LEDs) and photodetectors is discussed. The low‐dimensional perovskites are promising candidates for LED devices, mainly because of their high radiative recombination as a result of the confined low‐dimensional quantum well. Abstract : Peeling back the layers : The synthesis, properties, and structural orientation of low‐dimensional perovskite are surveyed. Controlling the number of perovskite layers can provide a confined structure with chemical and physical properties that are different from those of 3 D perovskite. The use of low‐dimensional perovskite in photovoltaic solar cells is discussed, as is its use in light‐emitting diodes and photodetectors.
