Crystal structure of CH 3 NH 3 PbX 3 perovskites (X=I, Br and/or Cl). The methylammonium cation (CH 3 NH 3 +) is surrounded by PbX 6 octahedra. [13]The name "perovskite solar cell" is derived from the ABX 3 crystal structure of the absorber materials, referred to as perovskite structure, where A and B are cations and X is an anion.
A tin-based perovskite solar cell (TPSCs) is a special type of perovskite solar cell, based on a tin perovskite structure (ASnX 3, where 'A' is a monovalent organic or inorganic cation (e.g., formamidinium (FA⁺), methylammonium (MA⁺), or cesium (Cs⁺)), tin is in its Sn (II) oxidation state and 'X' is a monovalent halogen anion (I⁻, Br⁻, Cl⁻) [1] [2] [3].
Since 2009, Miyasaka has been working on research and development of perovskite solar cell, therefore, he won the Clarivate Citation Laureates in 2017. [7] In 2017 Miyasaka was awarded the Hamakawa award for his contribution in photovoltaic science and technology development.
A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a type of photoelectric cell, a device whose electrical characteristics (such as current , voltage , or resistance ) vary when it is exposed to light.
A perovskite is a crystalline material of formula ABX 3 with a crystal structure similar to that of the mineral perovskite, this latter consisting of calcium titanium oxide (CaTiO 3). [2] The mineral was first discovered in the Ural mountains of Russia by Gustav Rose in 1839 and named after Russian mineralogist L. A. Perovski (1792–1856).
Solar cell efficiency of perovskite solar cells have increased from 3.8% in 2009 [47] to 25.2% in 2020 in single-junction architectures, [48] and, in silicon-based tandem cells, to 29.1%, [48] exceeding the maximum efficiency achieved in single-junction silicon solar cells.

A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current ...
