The back of the absorber is insulated by a 50 mm-thick fiberglass board. The absorber is protected by an aluminum casing, and a piece of borosilicate glass covers the top hole. Ten super-transparent aerogel tiles are placed on top of the absorber surface to replace the air gaps in traditional solar collectors.
Now researchers at MIT say they have accomplished the development of a material that comes very close to the “ideal” for solar absorption. The material is a two-dimensional metallic dielectric photonic crystal, and has the additional benefits of absorbing sunlight from a wide range of angles and withstanding extremely high temperatures.
It also has a very high thermal radiation intensity, reaching a high radiation efficiency of 94.4% at 1000 K, and a weighted average absorption efficiency of 98.3% at AM1.5. Additionally, the incidence angle insensitivity of our suggested solar absorber is good (0–60°) and polarization independence is good (0–90°).
As a result, when compared to other absorbers, our proposed absorber has excellent potential for use in the field of energy harvesting technologies, such as high absorption, broadband, and high-temperature-resistant metal-dielectric composite structures and solar thermal photovoltaics. 2.
