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.
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]
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.
Planar heterojunction perovskite solar cells can be manufactured in simplified device architectures (without complex nanostructures) using only vapor deposition. This technique produces 15% solar-to-electrical power conversion as measured under simulated full sunlight. [48]
One of many possible designs for a Heterojunction–Perovskite tandem solar cell. [102] Heterojunction–Perovskite tandem structures have been fabricated, with some research groups reporting a power conversion efficiency exceeding the 29.43% Shockley–Queisser limit for crystalline silicon. This feat has been achieved in both monolithic and 4 ...
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 ...

Perovskite solar cell technology can be tuned to red, green and blue by changing the metallic nanowire thickness to 8, 20 and 45 nm respectively. [19] Maximum power efficiencies of 10.12%, 8.17% and 7.72% were achieved by matching glass reflectance to the wavelength that the specific cell is designed to most optimally transmit.
