A calcium titanium oxide mineral composed of calcium titanate. In photovoltaics, perovskite refers to a class of materials with the same crystal structure that are being used to create highly efficient, low-cost solar cells.
Discovered in the Ural Mountains of Russia by Gustav Rose in 1839 and named after Russian mineralogist L.A. Perovski.
Perovskite solar cells are rapidly emerging as a competitor to silicon solar cells in the renewable energy market due to their high efficiency potential and low manufacturing costs.
