Default New PV - Perovskites

New technology of PV material based on perovskites to compete with ubiquitous silicon. Good efficiency, light weight, flexible and it can be applied on various surfaces.
Cost should be low; manufacturing is based on ink jet technology and it doesn’t require growing silicon in high temperature. Life expectancy 20 years.

Nice, but significant challenges ahead. Exposure to light and high heat..... key requirements.

When a profit making company introduces a product line, that will be a sign.

A. Perovski (1792–1856). The general chemical formula for perovskite compounds is ABX3, where 'A' and 'B' are two cations, often of very different sizes, and X is an anion (frequently oxide) that bonds to both cations. The 'A' atoms are generally larger than the 'B' atoms. The ideal cubic structure has the B cation in 6-fold coordination, surrounded by an octahedron of anions, and the A cation in 12-fold cuboctahedral coordination.”

“A perovskite solar cell (PSC[1]) is a type of solar cell which includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer.[2][3] Perovskite materials, such as methylammonium lead halides and all-inorganic caesium lead halide, are cheap to produce and simple to manufacture.
Solar cell efficiencies of devices using these materials have increased from 3.8% in 2009[4] to 25.5% in 2020 in single-junction architectures,[5] and, in silicon-based tandem cells, to 29.15%,[5] exceeding the maximum efficiency achieved in single-junction silicon solar cells. Perovskite solar cells are therefore the fastest-advancing solar technology as of 2016.[2] With the potential of achieving even higher efficiencies and very low production costs, perovskite solar cells have become commercially attractive.
The first commercial production line for perovskite solar cells was launched in May 2021 in Wroclaw, Poland, by Saule Technologies.[6]”
