Crossy Posted June 2, 2021 Share Posted June 2, 2021 Whilst looking for something else I found this:- https://www.sciencemag.org/news/2020/05/new-solar-panels-suck-water-air-cool-themselves-down Quote Like humans, solar panels don’t work well when overheated. Now, researchers have found a way to make them “sweat”—allowing them to cool themselves and increase their power output. It’s “a simple, elegant, and effective [way] to retrofit existing solar cell panels for an instant efficiency boost,” says Liangbing Hu, a materials scientist at the University of Maryland, College Park. Simple and elegant, will it ever catch on? Who knows? Link to comment Share on other sites More sharing options...

Interesting that the cooling power from the gel (295 W/M^2) exceeds the output power of even a 25% efficient PV cell that would make 250 W/M^2 in a 1KW/M^2 location. Maybe they're better off selling HVAC systems based on the gel technology. But that sounds fishy. Or maybe it's a poorly written abstract. The atmospheric water harvester photovoltaic cooling system provides an average cooling power of 295 W m–2 and lowers the temperature of a photovoltaic panel by at least 10 °C... https://www.nature.com/articles/s41893-020-0535-4 1 Link to comment Share on other sites More sharing options...
