Scientists create thin films which could lower solar energy costs


Scientists have created thin films made from barium zirconium sulfide (BaZrS3) and confirmed that the materials have alluring electronic and optical properties predicted by theorists.

The films combine exceptionally strong light absorption with good charge transport — two qualities that make them ideal for applications such as photovoltaics and light-emitting diodes (LEDs).

In solar panels, experimental results suggest that barium zirconium sulfide films would be much more efficient at converting sunlight into electricity than traditional silicon-based materials with identical thicknesses.
