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.
21 May – The first industrial commercial production line of perovskite solar panels, using an inkjet printing procedure, is launched in Poland. [ 59 ] 13 December – Researchers report the development of a database and analysis tool about perovskite solar cells which systematically integrates over 15,000 publications, in particular device ...
Perovskite MAPbX 3 thin films have been shown to be promising materials for optical gain applications such as lasers and optical amplifiers. [137] [138] Afterwards, the lasing properties of colloidal perovskite NCs such as CsPbX 3 nanocubes, [19] [139] MAPbBr 3 nanoplatelets [113] and FAPbX 3 nanocubes [83] [82] were also demonstrated.

Other promising materials and technologies for indoor photovoltaics include thin-film materials, III-V light harvesters, organic photovoltaics (OPV), dye-sensitized solar cells and perovskite solar cells. Thin-film materials, specifically CdTe, have displayed good performance under low light and diffuse conditions, with a band gap of 1.5 eV. [6]
The main obstacle to viable tin perovskite solar cells is the instability of tin's oxidation state Sn 2+, which is easily oxidized to the stabler Sn 4+. [10] In solar cell research, this process is called self-doping, [11] because the Sn 4+ acts as a p-dopant and reduces solar cell efficiency.
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 ...
Thin-film photovoltaic materials may possibly become attractive in the future, because of the reduced materials requirements and cost to manufacture modules consisting of thin-films as compared to silicon-based wafers. [118] In 2019 university labs at Oxford, Stanford and elsewhere reported perovskite solar cells with efficiencies of 20-25%. [119]
