A perovskite solar cell. A perovskite solar cell (PSC) is a type of solar cell 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 lattice of an antiperovskites (or inverse perovskites) is the same as that of the perovskite structure, but the anion and cation positions are switched. The typical perovskite structure is represented by the general formula ABX 3 , where A and B are cations and X is an anion.
Perovskite (pronunciation: / p ə ˈ r ɒ v s k aɪ t /) is a calcium titanium oxide mineral composed of calcium titanate (chemical formula Ca Ti O 3).Its name is also applied to the class of compounds which have the same type of crystal structure as CaTiO 3, known as the perovskite structure, which has a general chemical formula A 2+ B 4+ (X 2−) 3.

Perovskite nanocrystals can emit brightly when excited by ultraviolet or blue light. Their colors are tunable across the entire visible spectrum by changing the halide from chloride (UV/blue) to bromide (green) and iodide (red) [1]
Qcells said it had set a world record for the efficiency of a large-area silicon solar cell with a top layer of perovskite, the name for materials with a crystal structure that absorbs large ...
Methylammonium lead halides (MALHs) are solid compounds with perovskite structure and a chemical formula of [CH 3 NH 3] + Pb 2+ (X −) 3, where X = Cl, Br or I. They have potential applications in solar cells, [2] lasers, light-emitting diodes, photodetectors, radiation detectors, [3] [4] scintillator, [5] magneto-optical data storage [6] and ...
Ruddlesden-Popper (RP) phases are a type of perovskite structure that consists of two-dimensional perovskite-like slabs interleaved with cations.The general formula of an RP phase is A n+1 B n X 3n+1, where A and B are cations, X is an anion (e.g., oxygen), and n is the number of octahedral layers in the perovskite-like stack.

From January 2008 to April 2008, if you bought shares in companies when James Howard joined the board, and sold them when he left, you would have a -1.7 percent return on your investment, compared to a -4.9 percent return from the S&P 500.
