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.
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.
Solar-cell efficiencies of laboratory-scale devices using these materials have increased from 3.8% in 2009 [125] to 25.7% in 2021 in single-junction architectures, [126] [127] and, in silicon-based tandem cells, to 29.8%, [126] [128] exceeding the maximum efficiency achieved in single-junction silicon solar cells. Perovskite solar cells have ...
A paper titled "Ageing effects of perovskite solar cells under different environmental factors and electrical load conditions" published in 2018 in the journal [2] corresponded to a paper previously published in the journal Nature Energy as "Systematic investigation of the impact of operation conditions on the degradation behaviour of perovskite solar cells".

Solar cell efficiency of perovskite solar cells have increased from 3.8% in 2009 [47] to 25.2% in 2020 in single-junction architectures, [48] and, in silicon-based tandem cells, to 29.1%, [48] exceeding the maximum efficiency achieved in single-junction silicon solar cells.

However, the solar cells are prone to degradation due to volatility of the organic [CH 3 NH 3] + I − salt. The all-inorganic perovskite cesium lead iodide perovskite (CsPbI 3) circumvents this problem, but is itself phase-unstable, the low temperature solution methods of which have only been recently developed. [47]
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.
In 2021, she received the Lem's Planet Award in the technology category for her invention and commercialization of the printed perovskite-based solar cells. [13] In 2024, as the first Polish woman scientist, she received two European Inventor Awards presented by the European Patent Office. The first award was granted in the Small and Medium ...
