General description
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.
Application
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.
