Reply to comment by cope413 in Researchers designed a transparent window coating that could lower the temperature inside buildings, without expending a single watt of energy. This cooler may lead to an annual energy saving of up to 86.3 MJ/m² or 24 kWh/m² in hot climates by mossadnik

Interesting… is that due to reduced absorption in the near-UV range vs acrylic, polycarb, etc?

Yes, it has exceptional intrinsic thermal and UV stability (won't suffer degradation), and it has excellent transmittance.

It's also used as a boundary to prevent lead oxides from forming (called PDMS passivating). This is the main way that PDMS increases efficiency of solar cells.
