Scientists explore the physics of perovskite, a material with many potential technological applications
Publicado em 15 setembro 2021
Perovskite is one of the most widely studied materials because of its many potential applications. A particularly promising field is photovoltaics, which involves devices that efficiently convert light into electricity. The conversion efficiency of hybrid perovskite is now around 25.2%, surpassing that of commercial silicon-based solar cells.
An example of hybrid perovskite is methylammonium lead iodide (CH3NH3PbI3). It is called hybrid because the iodine atom's three negative ions (I-) [...]

Because of the small number of atoms, a quantum dot's properties lie between those of single atoms or molecules and bulk material with a huge number of atoms. By changing the nanoparticles' size and shape, it is possible to fine-tune their electronic and optical properties - how electrons bond and move through the material, and how light is absorbed and emitted by it.
