Energy breakthrough as new ‘transparent’ window coating help ditch ACs and slash bills

In a statement, the team, led by Eungkyu Lee, explained: “However, it’s difficult to design materials that can meet these criteria simultaneously and can also transmit visible light, meaning they don’t interfere with the view.”

Their “transparent radiative cooler” consisted of alternating thin layers of silicon dioxide, silicon nitride, aluminium oxide or titanium dioxide on a glass base, topped with a film of polydimethylsiloxane.

The researchers were then able to optimised the type, order and combination of layers of the coating with the help of machine learning.

They added: “This produced a coating design that, when fabricated, beat the performance of conventionally designed TRCs in addition to one of the best commercial heat-reduction glasses on the market.”
