- These cells represent the most exciting approach to build solar cells that are inexpensive and highly efficient.
- A perovskite solar cell is one that includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer.
- The terms “perovskite” and “perovskite structure” are often used interchangeably.
- Technically, a perovskite is a type of mineral that was first found in the Ural Mountains and named after Lev Perovski who was the founder of the Russian Geographical Society.
- A perovskite structure is any compound that has the same structure as the perovskite mineral.
- A perovskite is a material that has the same crystal structure as the mineral calcium titanium oxide, also known as Perovskite.
- Generally, perovskite compounds have a chemical formula ABX3, where ‘A’ and ‘B’ represent cations and X is an anion that bonds to both.
- Because of their unique crystal make-up, perovskites often display a number of interesting properties, including superconductivity, giant magnetoresistance, and ferroelectricity. It has only been recently that their applications to clean energy have drawn scientific attention.
- Within the last several years, perovskite solar cells have outpaced all other third-generation solar technologies in terms of efficiency.
