Descrizione generale

Strontium fluoride(SrF2) is a wideband gap anhydrous solid with excellent optical properties. It has a low refractive index, high transmission in the infrared and ultraviolet spectral range, and extremely low solubility in water. It is widely used as a coating material for lenses, optical windows, and prisms.

Applicazioni

Strontium fluoride can be used:

  • To produce an ultra-thin layer on the ZnO electron transport layer in inverted polymer solar cells. SrF2 thin layer enhances electron extraction efficiency and reduces carrier recombination loss, remarkably improving photovoltaic performance.
  • To prepare a highly luminescent Ce3+-doped SrF2 nanophosphor for dye-sensitized solar cells. These nanophosphors help to enhance light harvesting and power conversion efficiencies.
  • To fabricate non-toxic and dopant-free electron-selective contact for silicon solar cells. This contact has exceptional stability and thickness tolerance.

Lanthanide Ions as Photon Managers for Solar Cells

Spectral conversion for solar cells is an emerging concept in the field of photovoltaics, and it has the potential to increase significantly the efficiency of solar cells. Lanthanide ions are ideal candidates for spectral conversion, due to their high luminescence efficiencies and rich energy level structure that allows for great flexibility in the upconversion and downconversion of photons in a wide spectral region (NIR-VIS-UV).
