Perovskite solar cell
Alternative to silicon-based photovoltaics / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Perovskite solar cell?
Summarize this article for a 10 year old
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.[1][2] Perovskite materials, such as methylammonium lead halides and all-inorganic cesium lead halide, are cheap to produce and simple to manufacture.
Solar-cell efficiencies of laboratory-scale devices using these materials have increased from 3.8% in 2009[3] to 25.7% in 2021 in single-junction architectures,[4][5] and, in silicon-based tandem cells, to 29.8%,[4][6] exceeding the maximum efficiency achieved in single-junction silicon solar cells. Perovskite solar cells have therefore been the fastest-advancing solar technology as of 2016[update].[1] With the potential of achieving even higher efficiencies and very low production costs, perovskite solar cells have become commercially attractive. Core problems and research subjects include their short- and long-term stability.[7]
