The record for reflectance has been moved to 104%. Phys.org four hourrs ago:

phys.org/: Researchers claim photoluminescent aerogel has a visible light reflectance of 104%
Quote:
In this new study, the team in China reports that a passive radiative cooling material reflects more light than it receives due to its photoluminescence properties.

With photoluminescence, molecules absorb photons in the visible region and then excite their electrons to a higher state, resulting in light emission. Thus, if a material were to reflect 100% of the light that strikes it and additionally had photoluminescence, it could, in theory, reflect more light than it received.

To create such a material, the research team added freeze-dried salmon sperm DNA to a sample of gelatin. They allowed it to sublimate, leaving behind a layered aerogel that was highly compressed. The research team explains that it is held together via hydrogen bonds between phosphates in the DNA and amino acids in the gelatin.
So will it work (some might ask) with vaccinated Salmon sperm?
