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. [1] [2] Perovskite materials, such as methylammonium lead halides and all-inorganic cesium lead halide, are cheap to produce and ...
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 ...
Perovskite (structure) Structure of a perovskite with general chemical formula ABX 3. The red spheres are X atoms (usually oxygens), the blue spheres are B atoms (a smaller metal cation, such as Ti 4+ ), and the green spheres are the A atoms (a larger metal cation, such as Ca 2+ ). Pictured is the undistorted cubic structure; the symmetry is ...
Third-generation photovoltaic cell. Third-generation photovoltaic cells are solar cells that are potentially able to overcome the Shockley–Queisser limit of 31–41% power efficiency for single bandgap solar cells. This includes a range of alternatives to cells made of semiconducting p-n junctions ("first generation") and thin film cells ...
Thin-film solar cells are made by depositing one or more thin layers (thin films or TFs) of photovoltaic material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers to a few microns thick–much thinner than the wafers used in conventional crystalline silicon (c-Si) based solar cells, which can be up to 200 μm thick.

A tin-based perovskite solar cell is a special type of perovskite solar cell, based on a tin perovskite structure (ASnX 3, where 'A' is a 1+ cation and 'X' is a monovalent halogen anion ). As a technology, tin-based perovskite solar cells are still in the research phase, and are even less-studied than their counterpart, lead-based perovskite ...
Solar cell. A conventional crystalline silicon solar cell (as of 2005). Electrical contacts made from busbars (the larger silver-colored strips) and fingers (the smaller ones) are printed on the silicon wafer. Symbol of a Photovoltaic cell. A solar cell or photovoltaic cell ( PV cell) is an electronic device that converts the energy of light ...
