Perovskite Materials
Perovskite materials are defined by their unique ABX3 crystal structure, where "A" and "B" are cations and "X" is an anion.
The composition and stoichiometry of perovskite crystals can be altered to fit many different uses. They’re potential applications are only beginning to be explored, but some of the most popular uses of perovskites are in solar cell, LEDs, sensors and photodetectors.
Perovskites often utilize multiple A, B and X components in one crystal to achieve ideal material properties (e.g. for bandgap tuning, stability improvements). This stoichiometry is very important and impact device performance significantly. For most perovskite solar cell, precursor salts are mixed into a solution, which can be deposited through various thin film coating methods. This is known as a perovskite precursor solution or perovskite ink.

A perovskite solar cell is a thin film photovoltaic device. In these devices, perovskites absorb sunlight and convert it into electrical energy. Certain perovskites have fundamental properties which make them excellent at this. In some ways, perovskites are even better than the materials used in current solar cells.
