Description

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.

We are committed to bringing you Greener Alternative Products, which adhere to one of the four categories of Greener Alternatives. This is an enabling product and can be used with lanthanide ions to convert photon energy in solar cells, promoting energy efficiency. Click here for more information.

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.
