A perovskite solar cell is a type of solar cell that employs a metal halide perovskite compound as a light absorber. As the core material of a PSC, perovskite compounds have a general chemical formula of ABX 3 [26], where A and B are cations with various atomic radii (A is larger than B), and X is an anion.The crystal structure of organic-inorganic …
In general, photovoltaic performance of the perovskite solar cells is ascribed from their intrinsic properties like high absorption coefficient [23], tunable band gap [24], large carrier diffusion-length [25], ambipolar carrier-transport ability [26] and carrier mobility [27].Especially, organic-inorganic hybrid-perovskite (OHIP) materials are the …
The amazing advances made recently with perovskite photovoltaics will undoubtedly spur researchers to expand their investigations to other inorganic or organic …

Remarkably, such high-efficiency perovskite solar cells can be made from polycrystalline materials by solution processing. We want to: Understand basic material (e.g., doping and defect) and device properties related to halide perovskites
Planar perovskite solar cells (PSCs) can be made in either a regular n–i–p structure or an inverted p–i–n structure (see Fig. 1 for the meaning of n–i–p and …
Long-term device stability is the most pressing issue that impedes perovskite solar cell commercialization, given the achieved 22.7% efficiency. The perovskite absorber material itself has been heavily scrutinized for being prone to degrdn. by water, oxygen and
The two materials have different Fermi levels due to their different dopants, influencing the energy band level alignments to the other materials of the solar cell stack.
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) s 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.
