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.
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. [6]
Other possible solar cell types are organic solar cells, dye sensitized solar cells, perovskite solar cells, quantum dot solar cells, etc. The illuminated side of a solar cell generally has a transparent conducting film for allowing light to enter into the active material and to collect the generated charge carriers.
A paper titled "Ageing effects of perovskite solar cells under different environmental factors and electrical load conditions" published in 2018 in the journal [2] corresponded to a paper previously published in the journal Nature Energy as "Systematic investigation of the impact of operation conditions on the degradation behaviour of perovskite solar cells".

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].
Perovskite solar cells (not included in the chart) typically have significantly larger global warming potential than other thin-film materials in cradle-to-grave LCA, around 5-8x worse than mono crystalline silicon at 150g CO 2-eq /kWh. However, in grade-to-gate LCA, Perovskite cells perform 10-30% lower than mono-crystalline silicon ...
Solar cells can be thought of as visible light counterparts to radio receivers.A receiver consists of three basic parts; an antenna that converts the radio waves (light) into wave-like motions of electrons in the antenna material, an electronic valve that traps the electrons as they pop off the end of the antenna, and a tuner that amplifies electrons of a selected frequency.
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 ...
