The general formula for a perovskite is ABO3 where A and B are cations. The easiest way to visualize the structure is in terms of the BO6 octahedra which share corners infinitely in all 3 dimensions, making for a very nice and symmetric structure.
The crystal structure of perovskites refers to the arrangement of atoms in a compound with a general formula of ABX3 or ABO3, where A and B are cations and X is an anion. It is characterized by a classic cubic structure, with A representing monovalent cations, B representing divalent metal elements, and X representing halide or mixed halide anions.
The released electrons then move through an electron transport layer (ETL), facilitating their transport towards the battery. At the interface between the perovskite solar cell and the LIB, an electrolyte or electrolyte medium is present, allowing the migration of lithium ions.
Understanding the perovskite active layer is crucial, as its exceptional light absorption and charge transport properties are key to solar cell performance. The perovskite photoactive thin film has the chemical composition ABX₃, in which A is an organic or inorganic cation, B is a metal cation and X is a halide anion (Fig. 1a).
Metal halide perovskite solar cells are emerging as next-generation photovoltaics, offering an alternative to silicon-based cells. This Primer gives an overview of how to fabricate the photoactive layer, electrodes and charge transport layers in perovskite solar cells, including assembly into devices and scale-up for future commercial viability.
